Best Known (31, 31+49, s)-Nets in Base 3

(31, 31+49, 37)-Net over F₃ — Constructive and digital

Digital (31, 80, 37)-net over F₃, using

t-expansion [i] based on digital (27, 80, 37)-net over F₃, using
- net from sequence [i] based on digital (27, 36)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₃ with g(F)Â =Â 26, N(F)Â =Â 36, and 1 place with degree 2 [i] based on function field F/F₃ with g(F) = 26 and N(F) ≥ 36, using an explicitly constructive algebraic function field [i]

(31, 31+49, 42)-Net over F₃ — Digital

Digital (31, 80, 42)-net over F₃, using

t-expansion [i] based on digital (29, 80, 42)-net over F₃, using
- net from sequence [i] based on digital (29, 41)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 29 and N(F) ≥ 42, using

(31, 31+49, 132)-Net in Base 3 — Upper bound on s

There is no (31, 80, 133)-net in base 3, because

extracting embedded orthogonal array [i] would yield OA(3⁸⁰, 133, S₃, 49), but
- the linear programming bound shows that MÂ â‰¥ 21223 654940 747716 870153 549604 409912 091138 635334 644884 306688 767122 427377 344322 374868 328420 535820 061178 192292 178417 467677 / 142 600278 894934 337416 159250 039930 631375 413133 442674 819708 793351 208507 551154 176000 > 3⁸⁰ [i]
