(6, 68, 9319)-Net in Base 256 — Upper bound on s

There is no (6, 68, 9320)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 57 734669 086771 833256 227067 366403 401810 489742 602668 207813 399471 505894 378591 847896 876954 092255 049696 585024 586847 254305 570726 045571 310836 302999 342386 614451 948878 081476 > 256⁶⁸ [i]
