(258−125, 258, 298)-Net in Base 2 — Upper bound on s

There is no (133, 258, 299)-net in base 2, because

15 times m-reduction [i] would yield (133, 243, 299)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²⁴³, 299, S₂, 110), but
  - 1 times code embedding in larger space [i] would yield OA(2²⁴⁴, 300, S₂, 110), but
    - the linear programming bound shows that MÂ â‰¥ 727209 932038 995964 963694 786156 506719 769259 430085 807852 102717 045283 079365 167115 254635 995296 956416 / 21378 491075 472167 578125 > 2²⁴⁴ [i]
