(233−142, 233, 802)-Net in Base 4 — Upper bound on s

There is no (91, 233, 803)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 200 553112 226243 609371 213895 874788 887705 652492 585528 879532 437717 065199 366339 465959 317374 337991 593334 121937 490823 567180 257065 988063 261587 800320 > 4²³³ [i]
