      - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 41, N(F)Â =Â 32, 1 place with degree 2, and 2 places with degree 4 [i] based on function field F/F₂ with g(F) = 41 and N(F) ≥ 32, using an explicitly constructive algebraic function field [i]

Digital (105, 160, 108)-net over F₂, using

There is no (105, 160, 609)-net in base 2, because

1 times m-reduction [i] would yield (105, 159, 609)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 747992 684434 494234 048423 315901 996648 722730 010784 > 2¹⁵⁹ [i]
