Best Known (20, 20+38, s)-Nets in Base 5

(20, 20+38, 43)-Net over F₅ — Constructive and digital

Digital (20, 58, 43)-net over F₅, using

t-expansion [i] based on digital (18, 58, 43)-net over F₅, using
- net from sequence [i] based on digital (18, 42)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₅ with g(F)Â =Â 17, N(F)Â =Â 42, and 1 place with degree 2 [i] based on function field F/F₅ with g(F) = 17 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]

(20, 20+38, 256)-Net in Base 5 — Upper bound on s

There is no (20, 58, 257)-net in base 5, because

the generalized Rao bound for nets shows that 5^mÂ â‰¥ 36754 713853 196073 376064 249293 986348 664125 > 5⁵⁸ [i]
