(227−118, 227, 1528)-Net in Base 4 — Upper bound on s

There is no (109, 227, 1529)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 48068 081404 503069 689975 743766 118556 999884 743290 363752 706355 769135 622871 257922 989846 313454 795477 152051 824605 319050 646652 248689 730329 738880 > 4²²⁷ [i]
