(122, 250, 1796)-Net in Base 4 — Upper bound on s

There is no (122, 250, 1797)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 313553 717605 653818 771616 903413 494681 227667 090983 763108 811910 707788 323743 902001 223282 765616 387195 320058 159642 469874 818646 746126 847629 554021 465163 676100 > 4²⁵⁰ [i]
