- 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
(251−186, 251, 48)-Net over F2 — Digital
Digital (65, 251, 48)-net over F2, using
- net from sequence [i] based on digital (65, 47)-sequence over F2, using

(251−186, 251, 82)-Net in Base 2 — Upper bound on s
There is no (65, 251, 83)-net in base 2, because
- 9 times m-reduction [i] would yield (65, 242, 83)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2242, 83, S2, 3, 177), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 735 008378 947807 881106 651760 309054 102584 233301 100257 486578 588179 737729 826816 / 89 > 2242 [i]
- extracting embedded OOA [i] would yield OOA(2242, 83, S2, 3, 177), but
