- net from sequence [i] based on digital (2, 27)-sequence over F25, using
- digital (22, 34, 2604)-net over F25, using
- net defined by OOA [i] based on linear OOA(2534, 2604, F25, 12, 12) (dual of [(2604, 12), 31214, 13]-NRT-code), using
- OA 6-folding and stacking [i] based on linear OA(2534, 15624, F25, 12) (dual of [15624, 15590, 13]-code), using

(42−12, 42, 44509)-Net over F25 — Digital
Digital (30, 42, 44509)-net over F25, using
(42−12, 42, large)-Net in Base 25 — Upper bound on s
There is no (30, 42, large)-net in base 25, because
- 10 times m-reduction [i] would yield (30, 32, large)-net in base 25, but
