(187−126, 187, 446)-Net in Base 4 — Upper bound on s

There is no (61, 187, 447)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 42999 839017 746274 119479 776866 790282 679025 134122 695613 265493 114151 365950 946092 171542 462791 259540 029517 357568 873164 > 4¹⁸⁷ [i]
