(123, 123+134, 1697)-Net in Base 4 — Upper bound on s

There is no (123, 257, 1698)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 54100 912206 758824 176560 847597 562066 920226 601869 859075 845915 165624 489817 166658 665395 440836 469691 192537 720676 358953 618309 039112 542797 340870 292910 771873 435584 > 4²⁵⁷ [i]
