(227−104, 227, 2821)-Net in Base 4 — Upper bound on s

There is no (123, 227, 2822)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 46871 339946 277102 447345 973334 770280 067841 648908 976566 771129 031073 287298 978504 796417 595986 620038 378462 714937 235934 233112 990194 870250 775280 > 4²²⁷ [i]
