  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄₉ with g(F) = 1 and N(F) ≥ 64, using
    - sharp bound on the number of rational points on curves with genus 1 [i]

(22, 42, 2668)-Net in Base 7 — Upper bound on s

There is no (22, 42, 2669)-net in base 7, because

the generalized Rao bound for nets shows that 7^mÂ â‰¥ 312788 018162 292922 010938 816166 257129 > 7⁴² [i]
