(131, 131+119, 291)-Net in Base 2 — Upper bound on s

There is no (131, 250, 292)-net in base 2, because

11 times m-reduction [i] would yield (131, 239, 292)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²³⁹, 292, S₂, 108), but
  - the linear programming bound shows that MÂ â‰¥ 129 753212 264703 737764 759763 826530 014325 194921 459040 258227 297024 189374 782768 881401 211050 262528 / 138 951361 618522 578125 > 2²³⁹ [i]
