(21, 74, 43)-Net over F5 — Constructive and digital
Digital (21, 74, 43)-net over F5, using
- t-expansion [i] based on digital (18, 74, 43)-net over F5, using
- net from sequence [i] based on digital (18, 42)-sequence over F5, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F5 with g(F) = 17, N(F) = 42, and 1 place with degree 2 [i] based on function field F/F5 with g(F) = 17 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]
- net from sequence [i] based on digital (18, 42)-sequence over F5, using
(21, 74, 50)-Net over F5 — Digital
Digital (21, 74, 50)-net over F5, using
- net from sequence [i] based on digital (21, 49)-sequence over F5, using

(21, 74, 223)-Net in Base 5 — Upper bound on s
There is no (21, 74, 224)-net in base 5, because
- 1 times m-reduction [i] would yield (21, 73, 224)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 1121 310757 157949 219224 989111 816230 897338 534457 077249 > 573 [i]
