(127, 127+120, 2277)-Net in Base 4 — Upper bound on s

There is no (127, 247, 2278)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 52002 800403 788125 732398 742497 137803 121910 835939 292932 357966 186326 065063 104005 052444 116978 106259 716506 477619 007939 973406 028442 095455 759472 025629 815720 > 4²⁴⁷ [i]
