(143, 143+52, 115223)-Net in Base 4 — Upper bound on s

There is no (143, 195, 115224)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2521 878606 381232 432972 278063 788766 246087 690688 801438 710047 168042 384699 346508 655090 539977 172012 571008 988855 076340 517824 > 4¹⁹⁵ [i]
