Dammit, I'm REALLY late this time because of a basketball tournament. Doubt I would've figured this one out myself anyway, it requires a lot of knowledge of neopets. If anybody cares, I submitted 1,749,600 as well, which was the answer I got after double checking some answers from this thread

. It's one of the conundrums which are just too hard for me to solve myself and I'm too late for the trophy anyway.
