Maybe I'm not understanding the question (or the solution), but I thought it took 90 seconds to place the full set of pieces. So I would have used 90/16 in the calculations. Does this make sense?

*wonders if anyone is still around*

No, it doesn't make sense. 4! * 4! * 8! represents the number of combinations (all 16 pieces placed), not the number of pieces placed. It takes 90 seconds to place 16 pieces of each combination.

However, the optimal approach would not have you remove all of the pieces between combinations. You could lay 16 down, then swap two for two combinations in considerably less than 180 seconds.

Based on the wording, I'm sure they intend for you to consume 90 seconds per combination.

Its the center peices that are the trick not only can they go in each of 4 places but they can be oriented 4 ways - thats 4 times as many possible ways or is it 4 x 4 more different possible ways


You're absolutely right. We all overlooked the orientation part. The proposed answer must be multiplied by 4^4.

That makes the answer 6193152 days.

That's gonna piss off some folks.

2 men take turns walking and riding one horse that they share...walking speed 4km/hr..riding speed 12km/hr..one rides for some time and ties horse for the other walking fellow and continues walking......they keep going on like this alternately ..find time that the horse rests

You should probably post this in its own thread or in The World's First Riddle thread. This thread is for Lenny Conundrums.

The horse rests for 36 minutes each hour.

Sounds to me like you don't know how any of them are oriented. It doesn't seem very logical, but when are riddles logical? I would multiply the answer by 16^4 instead of 4^4

EDIT: bit of a typo, it should be 4^16, not 16^4. That's what I get for posting it on my midnight snack run Embarrassed

It all depends on what the pieces look like, how can you tell which ones are the edges (theoretically). Say for sake of argument it is because the edge and corner pieces form a square outline, an edge piece could look like:

┌──┐
├──┤
└──┘

Then the piece could have two possible orientations in an edge slot.

But overall with this one me is rather Confused about what they are actually meaning! It could just be that because you can tell it is an edge you know what way round it has to go as well?????

**EDIT Never mind, re-reading the conundrum

Quote:
You can tell by looking at the pieces which ones are the four corners, which ones are the eight side pieces, and which ones are the inside pieces. Otherwise, you can't tell where on the tablet they should go or how they should be oriented.

So I think therefore that does indeed state that the outer pieces could well be any way round...

Which would give an answer of 1585446912?

Correct me if i'm wrong but...
By using a formula from factor trees:
Possibilities (4)= P1 * P2 * P3

P1 would be 4 possible corners
P2 would be 8 possible sides
P3 would be 4 possible centers

So 4*8*4 = 128
128 * 90 secs = 11520 secs

There are 86400 secs in a day (60*60*24)

So that means that 11520 is less than half of 86400...and rounded to the nearest day that means 0 days

Answer: 0 Days
There...nothing simpler... maybe to easy, I might have missed something

You would be correct if you only had to place three pieces - one corner, one side, and one interior.

There are 4*3*2*1=4! ways to place the corner pieces. There are 8*7*6*5*4*3*2*1=8! ways to place the edge pieces. There are 4*3*2*1=4! ways to place the inside pieces. Then you also have to account for the fact that you don't know how (at least some of) the pieces are oriented.

This is very heavily related to the ongoing plot. The pieces have symbols on them. Most of them have one obvious direction. I think only one or two don't... lemme look...

WAIT, THIS IS UNFAIR Mad Which pieces are used? There are only twelve *different* symbols, but some have multiple orientations! They'd better be talking about a completely unrelated tablet, then!

For that matter, the pieces have 2 faces: that would make 8 orientations, 16 places for a multiplier of 8^16.

The wording of this puzzle sucks.

I was thinking that you would do something like this:

corners: 4x4=16
sides: 8x8=64
middle: 4x4=16

Put them all together: 16x64x16=16384

16384x90seconds=1474560

There are 86400seconds in a day = 17.06 rounded to 17 days

Hmmm
I tried 18....
Corners= 4*3*2*1=24
Edges=8*7*6*5*4*3*2*1=17280
Inside=4*3*2*1

Added together then mulitpiled by 90 seconds is 1559520

Divided by the seconds in a day 86400 gives 18.05 days....

Or at least I hope so as it's midnight and therefore did it by calculator and my husband's calculator just died... at least I think I did the right formula. (casts mind back to school maths over 13 years ago)

Just realised that someone said the tablets could be upside down or turned to 90 or 270° and therefore ignore my entry.... too late for me though as i submitted 18 :-P

what i did was

(4!)4+(4!)4+(8!)4

which equals about 168days after all the conversions. ... probably not right... but.... Meh...

Ok, well..I don't know how this works but what I'm trying is this:
In elementary school I learned to get all the combinations by multiplying all of it together. That gives you 256. ( 4x4x4x4)
Then I figure that 256/90 is roughly 2.8 days.
That is probably TOTALY wrong. And I really have no idea what I'm doing but making this up. And I know that that is simply assuming that you go 24 hrs straight, but I'm putting in three days.

Just remember, I am not the math guru. I am the grammar guru.

lol
if you want to do that...
you can orient any piece by 360^2
so multiple...

360^2*((4!*8!*4!)/(24*60*60))
assuming we rotate by a degree each time...
we could rotate by half a degree of course
so just stick with the easy anwer

I considered that. Since the pieces presumably have something written on one side, I decided that you probably know which way is up. That could certainly not be the case, however.

The only good thing about this puzzle is that once they announce the answer, we can work backwards and see what formula was right Confused
