(10, 82, 888)-Net over F25 — Upper bound on s (digital)
There is no digital (10, 82, 889)-net over F25, because
- 2 times m-reduction [i] would yield digital (10, 80, 889)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(2580, 889, F25, 70) (dual of [889, 809, 71]-code), but

(10, 82, 890)-Net in Base 25 — Upper bound on s
There is no (10, 82, 891)-net in base 25, because
