Best Known (79, 234, s)-Nets in Base 3

(79, 234, 54)-Net over F₃ — Constructive and digital

Digital (79, 234, 54)-net over F₃, using

net from sequence [i] based on digital (79, 53)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 53)-sequence over F₉, using
  - s-reduction based on digital (13, 63)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 13 and N(F) ≥ 64, using
      - a function field by GarcÃa and Quoos [i]

(79, 234, 84)-Net over F₃ — Digital

Digital (79, 234, 84)-net over F₃, using

t-expansion [i] based on digital (71, 234, 84)-net over F₃, using
- net from sequence [i] based on digital (71, 83)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 71 and N(F) ≥ 84, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(79, 234, 251)-Net over F₃ — Upper bound on s (digital)

There is no digital (79, 234, 252)-net over F₃, because

2 times m-reduction [i] would yield digital (79, 232, 252)-net over F₃, but
- extracting embedded orthogonal array [i] would yield linear OA(3²³², 252, F₃, 153) (dual of [252, 20, 154]-code), but
  - residual code [i] would yield OA(3⁷⁹, 98, S₃, 51), but
    - the linear programming bound shows that MÂ â‰¥ 37359 886424 244488 451760 980773 909770 698911 495751 / 677 763515 > 3⁷⁹ [i]

(79, 234, 338)-Net in Base 3 — Upper bound on s

There is no (79, 234, 339)-net in base 3, because

1 times m-reduction [i] would yield (79, 233, 339)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1621 108532 238382 661618 016188 195175 761003 386196 134080 774915 114174 795538 992673 023693 831536 896311 234425 223187 010895 > 3²³³ [i]
