(251−70, 251, 96303)-Net in Base 4 — Upper bound on s

There is no (181, 251, 96304)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 094416 141769 688628 166347 511113 133705 324465 878953 953144 593264 944187 039490 291114 769614 532979 924713 815186 937963 948259 426400 438228 720569 648639 498765 432045 > 4²⁵¹ [i]
