Best Known (115, 221, s)-Nets in Base 2

(115, 221, 57)-Net over F₂ — Constructive and digital

Digital (115, 221, 57)-net over F₂, using

t-expansion [i] based on digital (110, 221, 57)-net over F₂, using
- net from sequence [i] based on digital (110, 56)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 69, N(F)Â =Â 48, 1 place with degree 2, and 8 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]

(115, 221, 73)-Net over F₂ — Digital

Digital (115, 221, 73)-net over F₂, using

t-expansion [i] based on digital (114, 221, 73)-net over F₂, using
- net from sequence [i] based on digital (114, 72)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 114 and N(F) ≥ 73, using

(115, 221, 244)-Net in Base 2 — Upper bound on s

There is no (115, 221, 245)-net in base 2, because

2 times m-reduction [i] would yield (115, 219, 245)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²¹⁹, 245, S₂, 104), but
  - the linear programming bound shows that MÂ â‰¥ 4341 942115 300131 305544 557532 316409 359084 249150 486924 502348 546498 754871 558144 / 4286 038185 > 2²¹⁹ [i]
