(28, 57, 379)-Net over F27 — Digital
Digital (28, 57, 379)-net over F27, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(2757, 379, F27, 29) (dual of [379, 322, 30]-code), using
- discarding factors / shortening the dual code based on linear OA(2757, 728, F27, 29) (dual of [728, 671, 30]-code), using
(28, 57, 123570)-Net in Base 27 — Upper bound on s
There is no (28, 57, 123571)-net in base 27, because
- 1 times m-reduction [i] would yield (28, 56, 123571)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 143 349663 855173 955890 966620 110600 749912 000112 108429 554955 339732 451458 797715 207261 > 2756 [i]
