(97, 257, 812)-Net in Base 4 — Upper bound on s

There is no (97, 257, 813)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 58645 701061 453951 361236 132050 424506 879975 927702 860155 506568 654428 076126 112590 834338 134112 658903 829986 340458 372006 179647 765469 799187 530624 961910 009383 386120 > 4²⁵⁷ [i]
