(128, 258, 1994)-Net in Base 4 — Upper bound on s

There is no (128, 258, 1995)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 216214 653811 768437 803092 906826 740345 861483 088362 852650 371246 574509 612103 135553 474958 967397 811549 166324 165499 676160 965186 645315 967083 674605 009325 205001 664822 > 4²⁵⁸ [i]
