(19, 19+52, 14316)-Net in Base 64 — Upper bound on s

There is no (19, 71, 14317)-net in base 64, because

the generalized Rao bound for nets shows that 64^mÂ â‰¥ 173 606340 773201 054353 682459 143539 197736 926705 315167 949249 099159 557031 247227 471813 685010 523129 334278 451959 863178 006318 848063 564540 > 64⁷¹ [i]
