- discarding factors / shortening the dual code based on linear OA(349, 728, F3, 12) (dual of [728, 679, 13]-code), using
(49−12, 49, 11789)-Net in Base 3 — Upper bound on s
There is no (37, 49, 11790)-net in base 3, because
- the generalized Rao bound for nets shows that 3m ≥ 239411 699320 512359 725957 > 349 [i]
