(130, 258, 2146)-Net in Base 4 — Upper bound on s

There is no (130, 258, 2147)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 218393 520279 172057 648676 744838 469039 068940 774480 392606 731416 198515 633501 133391 907558 539561 144324 516166 095270 576988 074871 106879 411132 694354 559578 192684 588719 > 4²⁵⁸ [i]
