(238−112, 238, 2573)-Net in Base 4 — Upper bound on s

There is no (126, 238, 2574)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 195200 209194 579513 201203 546692 687577 371982 722886 684059 121068 460544 179567 765503 019564 298674 605315 076645 902595 888926 193186 238472 756069 483832 709664 > 4²³⁸ [i]
