(238−76, 238, 29513)-Net in Base 4 — Upper bound on s

There is no (162, 238, 29514)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 195238 314580 521957 777117 394452 115589 670438 955161 084614 608848 308599 460177 094119 172059 776010 561920 232907 560142 591743 112714 996308 692316 713134 856504 > 4²³⁸ [i]
