      - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 54, N(F)Â =Â 42, and 1 place with degree 6 [i] based on function field F/F₂ with g(F) = 54 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]

Digital (31, 115, 60)-net over F₄, using

There is no (31, 115, 131)-net in base 4, because

1 times m-reduction [i] would yield (31, 114, 131)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(4¹¹⁴, 131, S₄, 83), but
  - the linear programming bound shows that MÂ â‰¥ 86 644540 422655 853182 107056 136352 034587 797122 397724 053131 890431 260835 274263 887872 / 178263 764833 > 4¹¹⁴ [i]
