(251−124, 251, 2133)-Net in Base 4 — Upper bound on s

There is no (127, 251, 2134)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 368764 825951 466419 089628 075618 564568 151123 428142 146986 682369 034547 227133 705676 040214 920428 365269 819918 239993 921165 344495 847976 478975 744543 054893 676320 > 4²⁵¹ [i]
