(260−136, 260, 1692)-Net in Base 4 — Upper bound on s

There is no (124, 260, 1693)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 555240 163168 738946 158051 837889 540889 325944 449359 016408 943270 579282 681098 654350 719581 093412 891864 095367 907683 284782 575883 416694 639127 078878 685933 182286 859010 > 4²⁶⁰ [i]
