Information on Result #547786
There is no linear OA(3137, 161, F3, 89) (dual of [161, 24, 90]-code), because construction Y1 would yield
- OA(3136, 149, S3, 89), but
- the linear programming bound shows that M ≥ 6 385896 362423 839893 456186 755923 270794 744764 572661 578917 513381 685836 804369 / 75 686875 > 3136 [i]
- OA(324, 161, S3, 12), but
- discarding factors would yield OA(324, 124, S3, 12), but
- the Rao or (dual) Hamming bound shows that M ≥ 293147 842993 > 324 [i]
- discarding factors would yield OA(324, 124, S3, 12), but
Mode: Bound (linear).
