(231−110, 231, 2357)-Net in Base 4 — Upper bound on s

There is no (121, 231, 2358)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 009933 712662 919832 058708 112088 144649 998023 454773 639002 830220 378569 644406 111342 652070 587269 571853 911672 778564 701680 648802 285324 026592 772912 > 4²³¹ [i]
