(89−77, 89, 1059)-Net over F25 — Upper bound on s (digital)
There is no digital (12, 89, 1060)-net over F25, because
- 1 times m-reduction [i] would yield digital (12, 88, 1060)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(2588, 1060, F25, 76) (dual of [1060, 972, 77]-code), but

(89−77, 89, 1061)-Net in Base 25 — Upper bound on s
There is no (12, 89, 1062)-net in base 25, because
- 1 times m-reduction [i] would yield (12, 88, 1062)-net in base 25, but
