(9, 80, 104)-Net over F25 — Constructive and digital
Digital (9, 80, 104)-net over F25, using
- net from sequence [i] based on digital (9, 103)-sequence over F25, using

(9, 80, 805)-Net over F25 — Upper bound on s (digital)
There is no digital (9, 80, 806)-net over F25, because
- 5 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
