(128, 128+115, 279)-Net in Base 2 — Upper bound on s

There is no (128, 243, 280)-net in base 2, because

7 times m-reduction [i] would yield (128, 236, 280)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²³⁶, 280, S₂, 108), but
  - the linear programming bound shows that MÂ â‰¥ 41504 278412 335844 454047 491725 650645 432186 567323 902384 277507 042637 995046 295745 131031 035904 / 340479 332843 203125 > 2²³⁶ [i]
