(98, 98+140, 942)-Net in Base 4 — Upper bound on s

There is no (98, 238, 943)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 203110 120913 996736 788840 907064 375111 263944 299596 622482 744621 811027 970986 184060 733054 892711 185109 644700 360712 903783 572285 584140 872200 349314 311722 > 4²³⁸ [i]
