(246−136, 246, 1258)-Net in Base 4 — Upper bound on s

There is no (110, 246, 1259)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13193 158854 692258 856579 864816 591015 577358 444659 342451 817722 342572 447107 477749 454080 418203 585384 812182 076439 383953 390350 635805 172645 772964 027157 800026 > 4²⁴⁶ [i]
