Gilbertâ€“VarÅ¡amov bound [i]

(145, 145+110, 4354)-Net in Base 4 — Upper bound on s

There is no (145, 255, 4355)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3378 552877 133651 670002 076520 554422 653883 273639 342976 356424 381334 904668 103782 536766 707335 890982 119122 351547 225511 862611 752994 942896 241957 284222 212511 819264 > 4²⁵⁵ [i]
