(254−126, 254, 2115)-Net in Base 4 — Upper bound on s
There is no (128, 254, 2116)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 845 661878 966010 353311 832854 308279 822802 382017 796613 925986 142345 495133 549614 200916 361285 549987 432290 966374 435626 436589 735963 920132 096951 216761 185856 158960 > 4254 [i]
