- net from sequence [i] based on digital (1, 99)-sequence over F81, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F81 with g(F) = 1 and N(F) ≥ 100, using
- net from sequence [i] based on digital (1, 99)-sequence over F81, using
- digital (20, 41, 656)-net over F81, using
- net defined by OOA [i] based on linear OOA(8141, 656, F81, 21, 21) (dual of [(656, 21), 13735, 22]-NRT-code), using

(31, 52, 9522)-Net over F81 — Digital
Digital (31, 52, 9522)-net over F81, using
(31, 52, large)-Net in Base 81 — Upper bound on s
There is no (31, 52, large)-net in base 81, because
- 19 times m-reduction [i] would yield (31, 33, large)-net in base 81, but
