(35, 35+31, 6842353)-Net in Base 64 — Upper bound on s
There is no (35, 66, 6842354)-net in base 64, because
- 1 times m-reduction [i] would yield (35, 65, 6842354)-net in base 64, but
- the generalized Rao bound for nets shows that 64m ≥ 2521 730156 177206 759395 817229 814505 889826 377144 448457 386142 479118 257752 145385 207969 401676 078343 430257 436173 315721 868264 > 6465 [i]
