(108, 226, 1491)-Net in Base 4 — Upper bound on s

There is no (108, 226, 1492)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11839 330402 659847 416293 001071 988444 493778 995304 726759 694870 218573 169539 985495 189893 586477 573500 887332 379547 560930 325026 530044 548767 131752 > 4²²⁶ [i]
