(258−154, 258, 960)-Net in Base 4 — Upper bound on s

There is no (104, 258, 961)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 220538 453462 865129 191183 502816 614747 289318 455010 960966 325195 046579 989685 943442 662450 618312 149933 398514 377585 027508 632376 157889 876969 550412 620844 039270 756352 > 4²⁵⁸ [i]
