(101−90, 101, 971)-Net over F25 — Upper bound on s (digital)
There is no digital (11, 101, 972)-net over F25, because
- 14 times m-reduction [i] would yield digital (11, 87, 972)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(2587, 972, F25, 76) (dual of [972, 885, 77]-code), but

(101−90, 101, 973)-Net in Base 25 — Upper bound on s
There is no (11, 101, 974)-net in base 25, because
- 12 times m-reduction [i] would yield (11, 89, 974)-net in base 25, but
