(72−48, 72, 40778)-Net in Base 64 — Upper bound on s

There is no (24, 72, 40779)-net in base 64, because

the generalized Rao bound for nets shows that 64^mÂ â‰¥ 11091 272452 435961 222099 159422 101071 850590 078993 381831 285054 085138 515443 848533 957720 617323 476206 149477 944347 420750 173645 996660 636484 > 64⁷² [i]
