(76−56, 76, 14312)-Net in Base 64 — Upper bound on s

There is no (20, 76, 14313)-net in base 64, because

the generalized Rao bound for nets shows that 64^mÂ â‰¥ 186076 881910 423310 354338 099466 160816 564983 145043 962527 114346 101428 342381 967094 510417 329050 357175 990147 597889 834723 695319 974975 608003 939000 > 64⁷⁶ [i]
