(122, 254, 1704)-Net in Base 4 — Upper bound on s

There is no (122, 254, 1705)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 869 924361 362651 816153 050377 461681 524318 543710 412126 408269 436728 434826 549949 048437 685515 876784 038260 361996 229094 454621 357339 745033 932757 788547 971093 914200 > 4²⁵⁴ [i]
