(111, 111+136, 1285)-Net in Base 4 — Upper bound on s

There is no (111, 247, 1286)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 52636 546968 970427 385376 051496 579213 611543 725704 550835 641947 846605 133314 449118 974860 686239 406585 437998 476593 757134 525803 204173 357627 445649 034788 194620 > 4²⁴⁷ [i]
