(13, 65, 5474)-Net in Base 64 — Upper bound on s

There is no (13, 65, 5475)-net in base 64, because

the generalized Rao bound for nets shows that 64^mÂ â‰¥ 2522 375831 633405 829398 406814 375290 062312 171031 195084 204044 070740 165205 380901 002006 820864 175857 281077 436434 088209 053268 > 64⁶⁵ [i]
