(21, 21+29, 201248)-Net in Base 64 — Upper bound on s
There is no (21, 50, 201249)-net in base 64, because
- 1 times m-reduction [i] would yield (21, 49, 201249)-net in base 64, but
- the generalized Rao bound for nets shows that 64m ≥ 31829 855096 047865 091711 853487 959159 556217 087653 787767 964235 637383 561897 707502 064156 977744 > 6449 [i]
