(38, 38+48, 24)-Net over F2 — Constructive and digital
Digital (38, 86, 24)-net over F2, using
- t-expansion [i] based on digital (33, 86, 24)-net over F2, using
- net from sequence [i] based on digital (33, 23)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 33 and N(F) ≥ 24, using
- net from sequence [i] based on digital (33, 23)-sequence over F2, using
(38, 38+48, 30)-Net over F2 — Digital
Digital (38, 86, 30)-net over F2, using
- t-expansion [i] based on digital (36, 86, 30)-net over F2, using
- net from sequence [i] based on digital (36, 29)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 36 and N(F) ≥ 30, using

(38, 38+48, 84)-Net over F2 — Upper bound on s (digital)
There is no digital (38, 86, 85)-net over F2, because
- 8 times m-reduction [i] would yield digital (38, 78, 85)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(278, 85, F2, 40) (dual of [85, 7, 41]-code), but
- “Hel†bound on codes from Brouwer’s database [i]
- extracting embedded orthogonal array [i] would yield linear OA(278, 85, F2, 40) (dual of [85, 7, 41]-code), but
(38, 38+48, 86)-Net in Base 2 — Upper bound on s
There is no (38, 86, 87)-net in base 2, because
- the generalized Rao bound for nets shows that 2m ≥ 91 134941 234206 130139 887912 > 286 [i]
