Information on Result #547762

There is no linear OA(3116, 197, F3, 72) (dual of [197, 81, 73]-code), because construction Y1 would yield
  1. OA(3115, 148, S3, 72), but
    • the linear programming bound shows that M ≥ 15138 532736 321222 240484 923894 686292 145850 190102 104613 028724 231594 313752 692357 / 1981 901463 555581 678825 > 3115 [i]
  2. OA(381, 197, S3, 49), but
    • discarding factors would yield OA(381, 145, S3, 49), but
