Information on Result #547789
There is no linear OA(3139, 160, F3, 91) (dual of [160, 21, 92]-code), because construction Y1 would yield
- OA(3138, 150, S3, 91), but
- the linear programming bound shows that M ≥ 13 106423 371120 876472 986931 421169 566720 811359 868949 528224 695915 065174 686944 / 17 599301 > 3138 [i]
- OA(321, 160, S3, 10), but
- discarding factors would yield OA(321, 133, S3, 10), but
- the Rao or (dual) Hamming bound shows that M ≥ 10487 287539 > 321 [i]
- discarding factors would yield OA(321, 133, S3, 10), but
Mode: Bound (linear).
