(258−126, 258, 2315)-Net in Base 4 — Upper bound on s

There is no (132, 258, 2316)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 220021 497046 232208 092147 567160 584223 040972 678560 484286 571100 417605 869068 156922 117623 376075 434255 194560 992895 750210 175445 106510 965481 043545 132671 361289 868480 > 4²⁵⁸ [i]
