Best Known (4, 7, s)-Nets in Base 25
(4, 7, 391875)-Net over F25 — Constructive and digital
Digital (4, 7, 391875)-net over F25, using
- net defined by OOA [i] based on linear OOA(257, 391875, F25, 3, 3) (dual of [(391875, 3), 1175618, 4]-NRT-code), using
- appending kth column [i] based on linear OOA(257, 391875, F25, 2, 3) (dual of [(391875, 2), 783743, 4]-NRT-code), using
(4, 7, large)-Net in Base 25 — Upper bound on s
There is no (4, 7, large)-net in base 25, because
- 1 times m-reduction [i] would yield (4, 6, large)-net in base 25, but
