(93, 217, 970)-Net in Base 4 — Upper bound on s

There is no (93, 217, 971)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 44547 292319 267703 233692 895170 487804 492568 808327 528549 584339 731235 502077 503913 607981 203396 384468 007722 375500 807872 020452 790454 463440 > 4²¹⁷ [i]
