Re: THE project euler thread

yeah, i never said what those were, i'm sorry
a_p is just the number that is divisible by p in whatever set we're looking at (since we're supposed to be looking at coprime sets there is exactly one...

Re: THE project euler thread

17 is brought back as part of Co(95)
95+17 > 85+19
it's the exact same phenomenon that occurs with 21 and 5 replacing 15 and 7

5 : [4, 3, 5]
6 < 4+3, don't insert

8 has one prime factor, insert
