Gilbertâ€“VarÅ¡amov bound [i]

(141, 141+98, 5464)-Net in Base 4 — Upper bound on s

There is no (141, 239, 5465)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 781265 225877 563070 644992 353979 401169 873283 466754 657625 149339 993125 822506 000979 433192 914084 825179 552077 724005 328381 453529 602269 704467 464825 603528 > 4²³⁹ [i]
