(91−79, 91, 1057)-Net over F25 — Upper bound on s (digital)
There is no digital (12, 91, 1058)-net over F25, because
- 1 times m-reduction [i] would yield digital (12, 90, 1058)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(2590, 1058, F25, 78) (dual of [1058, 968, 79]-code), but

(91−79, 91, 1058)-Net in Base 25 — Upper bound on s
There is no (12, 91, 1059)-net in base 25, because
- 1 times m-reduction [i] would yield (12, 90, 1059)-net in base 25, but
- the generalized Rao bound for nets shows that 25m ≥ 653003 603352 508564 293415 991903 094814 008180 915002 474377 452172 570287 390422 436005 753256 564305 303225 560238 203040 220535 022616 847225 > 2590 [i]
