(161, 161+72, 37492)-Net in Base 4 — Upper bound on s

There is no (161, 233, 37493)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 190 690869 833617 148128 527169 518047 766337 906925 637967 799040 881042 130432 139088 310962 790220 230342 480124 674324 881207 009772 464605 795661 873682 564805 > 4²³³ [i]
