(105, 105+126, 1255)-Net in Base 4 — Upper bound on s

There is no (105, 231, 1256)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 345165 462753 552491 955692 209721 328754 334917 072659 120729 886499 302025 873759 654921 647629 180485 087415 710960 702528 122038 861929 987085 243671 463640 > 4²³¹ [i]
