(63−33, 63, 149145)-Net in Base 32 — Upper bound on s
There is no (30, 63, 149146)-net in base 32, because
- 1 times m-reduction [i] would yield (30, 62, 149146)-net in base 32, but
- the generalized Rao bound for nets shows that 32m ≥ 2086 059685 247336 101707 795058 001211 362153 845752 825356 718520 542360 717972 230541 672048 938739 068807 > 3262 [i]
