(67, 220, 43)-Net over F2 — Constructive and digital
Digital (67, 220, 43)-net over F2, using
- t-expansion [i] based on digital (59, 220, 43)-net over F2, using
- net from sequence [i] based on digital (59, 42)-sequence over F2, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F2 with g(F) = 54, N(F) = 42, and 1 place with degree 6 [i] based on function field F/F2 with g(F) = 54 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]
- net from sequence [i] based on digital (59, 42)-sequence over F2, using
(67, 220, 48)-Net over F2 — Digital

(67, 220, 98)-Net in Base 2 — Upper bound on s
There is no (67, 220, 99)-net in base 2, because
- 29 times m-reduction [i] would yield (67, 191, 99)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2191, 99, S2, 2, 124), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 100433 627766 186892 221372 630771 322662 657637 687111 424552 206336 / 25 > 2191 [i]
- extracting embedded OOA [i] would yield OOA(2191, 99, S2, 2, 124), but
