(93, 93+162, 746)-Net in Base 4 — Upper bound on s

There is no (93, 255, 747)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3603 519266 354286 814381 711007 705630 184322 064169 550378 724443 686245 264691 407547 609722 448541 944222 723323 793515 989204 344498 052493 878750 301986 612874 214889 700452 > 4²⁵⁵ [i]
