(113, 148, 464)-Net over F₃ — Constructive and digital

Digital (113, 148, 464)-net over F₃, using

trace code for nets [i] based on digital (2, 37, 116)-net over F₈₁, using
- net from sequence [i] based on digital (2, 115)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 2 and N(F) ≥ 116, using
    - a function field by SÃ©mirat [i]

(113, 148, 830)-Net over F₃ — Digital

Digital (113, 148, 830)-net over F₃, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3¹⁴⁸, 830, F₃, 35) (dual of [830, 682, 36]-code), using
- 83 step VarÅ¡amovâ€“Edel lengthening with (r_i)Â = (3, 1, 1, 0, 0, 1, 0, 0, 0, 1, 4 times 0, 1, 7 times 0, 1, 9 times 0, 1, 13 times 0, 1, 16 times 0, 1, 19 times 0) [i] based on linear OA(3¹³⁶, 735, F₃, 35) (dual of [735, 599, 36]-code), using
  - constructionÂ X applied to C_e(34) âŠ‚ C_e(33) [i] based on
    1. linear OA(3¹³⁶, 729, F₃, 35) (dual of [729, 593, 36]-code), using an extension C_e(34) of the primitive narrow-sense BCH-code C(I) with length 728Â = 3⁶âˆ’1, defining interval IÂ =Â [1,34], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 35 [i]
    2. linear OA(3¹³⁰, 729, F₃, 34) (dual of [729, 599, 35]-code), using an extension C_e(33) of the primitive narrow-sense BCH-code C(I) with length 728Â = 3⁶âˆ’1, defining interval IÂ =Â [1,33], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 34 [i]
    3. linear OA(3⁰, 6, F₃, 0) (dual of [6, 6, 1]-code), using
      - discarding factors / shortening the dual code based on linear OA(3⁰, s, F₃, 0) (dual of [s, s, 1]-code) with arbitrarily large s, using
        OA with only one run / dual of code without redundancy [i]

(113, 148, 47913)-Net in Base 3 — Upper bound on s

There is no (113, 148, 47914)-net in base 3, because

1 times m-reduction [i] would yield (113, 147, 47914)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 13703 905524 759882 509865 768622 113732 812491 553418 491057 847785 249993 394357 > 3¹⁴⁷ [i]
