Digital (27, 110, 55)-net over F₄, using

t-expansion [i] based on digital (26, 110, 55)-net over F₄, using
- net from sequence [i] based on digital (26, 54)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 26 and N(F) ≥ 55, using

(110−83, 110, 115)-Net in Base 4 — Upper bound on s

There is no (27, 110, 116)-net in base 4, because

8 times m-reduction [i] would yield (27, 102, 116)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(4¹⁰², 116, S₄, 75), but
  - the linear programming bound shows that MÂ â‰¥ 173566 451646 449122 083079 076441 789443 549958 833470 789796 847564 973808 812032 / 4774 621397 > 4¹⁰² [i]
