(111, 111+146, 1170)-Net in Base 4 — Upper bound on s

There is no (111, 257, 1171)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 56053 019686 016110 636103 608087 187158 950139 284010 584703 354262 921777 019387 711787 884158 786530 975349 631156 060626 273208 442759 178710 484072 867810 808851 867571 403240 > 4²⁵⁷ [i]
