(238−158, 238, 593)-Net in Base 4 — Upper bound on s

There is no (80, 238, 594)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 212527 910509 594041 127718 019750 436281 265234 160911 034160 766730 338169 110876 911161 787884 662623 087294 174232 946820 472785 783010 574250 665300 260691 745688 > 4²³⁸ [i]
