MinT - Best Known (30−25, 30, s)-Nets in Base 4

Best Known (30−25, 30, s)-Nets in Base 4

(30−25, 30, 17)-Net over F₄ — Constructive and digital

Digital (5, 30, 17)-net over F₄, using

net from sequence [i] based on digital (5, 16)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 5 and N(F) ≥ 17, using
  - an explicitly constructive algebraic function field [i]

(30−25, 30, 24)-Net in Base 4 — Upper bound on s

There is no (5, 30, 25)-net in base 4, because

3 times m-reduction [i] would yield (5, 27, 25)-net in base 4, but
- extracting embedded OOA [i] would yield OOA(4²⁷, 25, S₄, 2, 22), but
  - the linear programming bound for OOAs shows that MÂ â‰¥ 70867 229606 019130 720256 / 3 858899 > 4²⁷ [i]
