What's up.
For the still unknown numbers:
M9 = F(512) = F(496)+F(480).
M10 =F(1024) = 2*F(992).
All Mn values, n even, are even.
All calculated with the x64-86 OpenMP Windows10 EXE.
Released freebie on: https://github.com/JOSMAN-UE
The program can calculate each F(n), with n multiple of 4 between 8 and 256.
Time spent is not O(n). Some numbers require computer power. You guys for real: A whiz. SaysME your score.
