(82−61, 82, 14377)-Net in Base 64 — Upper bound on s

There is no (21, 82, 14378)-net in base 64, because

1 times m-reduction [i] would yield (21, 81, 14378)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 200 019262 134009 494489 502031 747770 019664 542030 349048 188272 964904 431442 051861 562414 781493 214350 764950 739030 636937 186232 948213 824248 058705 857001 209936 > 64⁸¹ [i]
