(109, 109+134, 1257)-Net in Base 4 — Upper bound on s

There is no (109, 243, 1258)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 207 484169 802142 176818 477513 252139 650663 427248 676999 446918 097108 433431 830038 840987 145989 960176 785947 403746 559619 652735 020410 066832 045075 712324 638604 > 4²⁴³ [i]
