(158, 258, 8260)-Net in Base 4 — Upper bound on s

There is no (158, 258, 8261)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 214959 410438 824253 579781 450473 897714 471579 050161 750729 468653 000675 578419 233827 693805 032681 772163 339220 540400 832264 929963 376114 698971 230271 130248 928711 673256 > 4²⁵⁸ [i]
