(246−118, 246, 2414)-Net in Base 4 — Upper bound on s
There is no (128, 246, 2415)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 12813 937835 661554 792255 349579 675287 250051 146531 353457 351750 018319 637708 550856 319275 500649 689673 295574 087128 538804 141910 662315 515907 154683 374358 005120 > 4246 [i]
