(92−83, 92, 104)-Net over F25 — Constructive and digital
Digital (9, 92, 104)-net over F25, using
- net from sequence [i] based on digital (9, 103)-sequence over F25, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F25 with g(F) = 9 and N(F) ≥ 104, using
(92−83, 92, 805)-Net over F25 — Upper bound on s (digital)
There is no digital (9, 92, 806)-net over F25, because
- 17 times m-reduction [i] would yield digital (9, 75, 806)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(2575, 806, F25, 66) (dual of [806, 731, 67]-code), but

(92−83, 92, 806)-Net in Base 25 — Upper bound on s
There is no (9, 92, 807)-net in base 25, because
- 19 times m-reduction [i] would yield (9, 73, 807)-net in base 25, but
