(143, 143+68, 24557)-Net in Base 4 — Upper bound on s

There is no (143, 211, 24558)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 845223 941463 000657 736163 102719 026096 519534 263019 094227 906431 386119 457969 838789 803403 284514 640368 385485 164708 552001 713407 604410 > 4²¹¹ [i]
