We have two sequences:
n°1 : 6-10-14-15-21-22-26-33-34-35- ...
n°2 : 5-7-9-8-10-13-15-14-19-12-...

Give the result in next form:
a11-a12-a13-a14-b11-b12-b13-b14
Where a is first sequence and b is second.

@nellu,

nice try, but none of the other prime multiples involve squaring primes

so 7 x 7 looks a bit lonely given you're already up to

2 x 19, 3 x 13, 2 x 23, for your first 3 terms and yet the preceding sequence

does not contain 2, 3, 4, 5 or 6 squared
