(121, 121+95, 298)-Net in Base 2 — Upper bound on s

There is no (121, 216, 299)-net in base 2, because

1 times m-reduction [i] would yield (121, 215, 299)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²¹⁵, 299, S₂, 94), but
  - adding a parity check bit [i] would yield OA(2²¹⁶, 300, S₂, 95), but
    - the linear programming bound shows that MÂ â‰¥ 872407 680551 113098 866799 953294 886066 311827 924058 628412 428016 149220 115296 187426 023936 653562 740736 / 5 938078 052347 021578 779474 608305 > 2²¹⁶ [i]
