(91, 91+166, 706)-Net in Base 4 — Upper bound on s

There is no (91, 257, 707)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 55539 481270 610870 718808 462176 156023 817286 911760 776812 454956 702469 054200 671973 622352 128085 134734 330696 069464 892041 927607 556372 046541 002280 875529 791557 191392 > 4²⁵⁷ [i]
