(99−87, 99, 1055)-Net over F25 — Upper bound on s (digital)
There is no digital (12, 99, 1056)-net over F25, because
- 7 times m-reduction [i] would yield digital (12, 92, 1056)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(2592, 1056, F25, 80) (dual of [1056, 964, 81]-code), but

(99−87, 99, 1056)-Net in Base 25 — Upper bound on s
There is no (12, 99, 1057)-net in base 25, because
- 1 times m-reduction [i] would yield (12, 98, 1057)-net in base 25, but
- the generalized Rao bound for nets shows that 25m ≥ 99931 553995 410600 915510 329562 529837 879229 429754 477829 461184 370325 276741 690311 479173 064112 823773 171335 589274 557819 242658 121926 099542 849225 > 2598 [i]
