(258−176, 258, 581)-Net in Base 4 — Upper bound on s

There is no (82, 258, 582)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 232476 123054 534505 491596 506286 778790 572199 028432 420058 748563 418195 796029 233997 136485 855902 028411 809876 524508 382119 302208 428385 363893 327664 607745 165745 119680 > 4²⁵⁸ [i]
