Best Known (98, 98+93, s)-Nets in Base 2

Digital (98, 191, 54)-net over F₂, using

t-expansion [i] based on digital (95, 191, 54)-net over F₂, using
- net from sequence [i] based on digital (95, 53)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 69, N(F)Â =Â 48, 1 place with degree 2, and 5 places with degree 6 [i] based on function field F/F₂ with g(F) = 69 and N(F) ≥ 48, using an explicitly constructive algebraic function field [i]

Digital (98, 191, 65)-net over F₂, using

t-expansion [i] based on digital (95, 191, 65)-net over F₂, using
- net from sequence [i] based on digital (95, 64)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 95 and N(F) ≥ 65, using
    - Drinfeld modules of rank 1 [i]

There is no digital (98, 191, 216)-net over F₂, because

1 times m-reduction [i] would yield digital (98, 190, 216)-net over F₂, but
- extracting embedded orthogonal array [i] would yield linear OA(2¹⁹⁰, 216, F₂, 92) (dual of [216, 26, 93]-code), but
  - 4 times code embedding in larger space [i] would yield linear OA(2¹⁹⁴, 220, F₂, 92) (dual of [220, 26, 93]-code), but
    - adding a parity check bit [i] would yield linear OA(2¹⁹⁵, 221, F₂, 93) (dual of [221, 26, 94]-code), but
      - â€œBKâ€ bound on codes from Brouwerâ€™s database [i]

There is no (98, 191, 253)-net in base 2, because

1 times m-reduction [i] would yield (98, 190, 253)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1613 547621 776236 058714 049079 657924 119194 373050 827301 700908 > 2¹⁹⁰ [i]
