- net from sequence [i] based on digital (80, 50)-sequence over F2, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F2 with g(F) = 69, N(F) = 48, 1 place with degree 2, and 2 places with degree 6 [i] based on function field F/F2 with g(F) = 69 and N(F) ≥ 48, using an explicitly constructive algebraic function field [i]
- net from sequence [i] based on digital (80, 50)-sequence over F2, using
(159−76, 159, 57)-Net over F2 — Digital
Digital (83, 159, 57)-net over F2, using
- net from sequence [i] based on digital (83, 56)-sequence over F2, using

(159−76, 159, 191)-Net over F2 — Upper bound on s (digital)
There is no digital (83, 159, 192)-net over F2, because
- extracting embedded orthogonal array [i] would yield linear OA(2159, 192, F2, 76) (dual of [192, 33, 77]-code), but
- 4 times code embedding in larger space [i] would yield linear OA(2163, 196, F2, 76) (dual of [196, 33, 77]-code), but
- adding a parity check bit [i] would yield linear OA(2164, 197, F2, 77) (dual of [197, 33, 78]-code), but
- 4 times code embedding in larger space [i] would yield linear OA(2163, 196, F2, 76) (dual of [196, 33, 77]-code), but
(159−76, 159, 221)-Net in Base 2 — Upper bound on s
There is no (83, 159, 222)-net in base 2, because
- the generalized Rao bound for nets shows that 2m ≥ 791095 274832 259828 166625 892677 646787 828250 063800 > 2159 [i]
