(243−132, 243, 1341)-Net in Base 4 — Upper bound on s

There is no (111, 243, 1342)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 204 400516 029960 102982 418060 988296 975501 703986 198968 788317 122546 112554 466018 306568 760673 736348 090627 935739 884382 378659 080311 953140 815829 371705 245080 > 4²⁴³ [i]
