(109, 253, 1143)-Net in Base 4 — Upper bound on s

There is no (109, 253, 1144)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 213 493492 999197 977021 415151 493979 046966 307911 374601 050306 731119 900081 132640 885930 941719 230316 528416 234926 243405 264507 628100 667284 383052 323081 660826 324970 > 4²⁵³ [i]
