(21, 84, 13492)-Net in Base 64 — Upper bound on s

There is no (21, 84, 13493)-net in base 64, because

1 times m-reduction [i] would yield (21, 83, 13493)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 819114 834457 537244 754457 368995 638957 987705 055968 452981 167330 192160 087458 350451 484519 911598 876363 148273 736522 247589 334772 562157 034957 491343 351225 225760 > 64⁸³ [i]
