(245−113, 245, 296)-Net in Base 2 — Upper bound on s

There is no (132, 245, 297)-net in base 2, because

5 times m-reduction [i] would yield (132, 240, 297)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²⁴⁰, 297, S₂, 108), but
  - the linear programming bound shows that MÂ â‰¥ 28020 398795 768772 015654 276848 365160 205592 563190 101250 876110 646415 347830 039205 258520 634937 311232 / 15527 302685 925212 739375 > 2²⁴⁰ [i]
