- base expansion [i] based on digital (48, 34)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 41, N(F)Â =Â 32, 1 place with degree 2, and 2 places with degree 4 [i] based on function field F/F₂ with g(F) = 41 and N(F) ≥ 32, using an explicitly constructive algebraic function field [i]

(24, 24+144, 49)-Net over F₄ — Digital

Digital (24, 168, 49)-net over F₄, using

net from sequence [i] based on digital (24, 48)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 24 and N(F) ≥ 49, using

(24, 24+144, 103)-Net in Base 4 — Upper bound on s

There is no (24, 168, 104)-net in base 4, because

74 times m-reduction [i] would yield (24, 94, 104)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(4⁹⁴, 104, S₄, 70), but
  - the linear programming bound shows that MÂ â‰¥ 2905 343984 020254 418179 867462 952821 985360 143012 759289 446224 887808 / 6 994423 > 4⁹⁴ [i]
