(22, 68, 32732)-Net in Base 64 — Upper bound on s

There is no (22, 68, 32733)-net in base 64, because

the generalized Rao bound for nets shows that 64^mÂ â‰¥ 661 422802 232208 542293 194809 250028 494861 535310 030235 604937 773049 635152 458163 013202 216739 577710 121452 551320 632325 820434 575160 > 64⁶⁸ [i]
