(259−132, 259, 1898)-Net in Base 4 — Upper bound on s

There is no (127, 259, 1899)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 869788 806108 278461 541052 124838 181931 652412 055179 902321 545047 687346 782668 949513 409458 805060 619951 283947 382320 425551 986659 908572 450475 067364 496416 264782 050943 > 4²⁵⁹ [i]
