(145, 145+60, 52184)-Net in Base 4 — Upper bound on s

There is no (145, 205, 52185)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2645 224193 610294 093499 415412 896707 931878 679034 218298 096311 959019 650264 514495 683539 071542 528556 784362 106510 285956 716856 657440 > 4²⁰⁵ [i]
