(21, 21+26, 1369)-Net over F256 — Digital
Digital (21, 47, 1369)-net over F256, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(25647, 1369, F256, 26) (dual of [1369, 1322, 27]-code), using
(21, 21+26, large)-Net in Base 256 — Upper bound on s
There is no (21, 47, large)-net in base 256, because
- 24 times m-reduction [i] would yield (21, 23, large)-net in base 256, but
