(32, 32+31, 344891)-Net in Base 32 — Upper bound on s
There is no (32, 63, 344892)-net in base 32, because
- 1 times m-reduction [i] would yield (32, 62, 344892)-net in base 32, but
- the generalized Rao bound for nets shows that 32m ≥ 2085 998359 886945 634067 050598 033485 419600 234807 543777 940207 579850 102525 866349 767131 981026 789108 > 3262 [i]
