(37, 37+46, 24)-Net over F2 — Constructive and digital
Digital (37, 83, 24)-net over F2, using
- t-expansion [i] based on digital (33, 83, 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
(37, 37+46, 30)-Net over F2 — Digital
Digital (37, 83, 30)-net over F2, using
- t-expansion [i] based on digital (36, 83, 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

(37, 37+46, 82)-Net over F2 — Upper bound on s (digital)
There is no digital (37, 83, 83)-net over F2, because
- 6 times m-reduction [i] would yield digital (37, 77, 83)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(277, 83, F2, 40) (dual of [83, 6, 41]-code), but
(37, 37+46, 83)-Net in Base 2 — Upper bound on s
There is no (37, 83, 84)-net in base 2, because
- 4 times m-reduction [i] would yield (37, 79, 84)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(279, 84, S2, 42), but
- adding a parity check bit [i] would yield OA(280, 85, S2, 43), but
- the (dual) Plotkin bound shows that M ≥ 14 507109 835375 550096 474112 / 11 > 280 [i]
- adding a parity check bit [i] would yield OA(280, 85, S2, 43), but
- extracting embedded orthogonal array [i] would yield OA(279, 84, S2, 42), but
