- net from sequence [i] based on digital (2, 27)-sequence over F25, using
- digital (42, 64, 1420)-net over F25, using
- net defined by OOA [i] based on linear OOA(2564, 1420, F25, 22, 22) (dual of [(1420, 22), 31176, 23]-NRT-code), using
- OA 11-folding and stacking [i] based on linear OA(2564, 15620, F25, 22) (dual of [15620, 15556, 23]-code), using

(77−22, 77, 48323)-Net over F25 — Digital
Digital (55, 77, 48323)-net over F25, using
(77−22, 77, large)-Net in Base 25 — Upper bound on s
There is no (55, 77, large)-net in base 25, because
- 20 times m-reduction [i] would yield (55, 57, large)-net in base 25, but
