Information on Result #580985
There is no linear OOA(329, 47, F3, 4, 19) (dual of [(47, 4), 159, 20]-NRT-code), because 2 times depth reduction would yield linear OOA(329, 47, F3, 2, 19) (dual of [(47, 2), 65, 20]-NRT-code), but
- 1 step m-reduction [i] would yield linear OA(328, 47, F3, 18) (dual of [47, 19, 19]-code), but
- construction Y1 [i] would yield
- linear OA(327, 35, F3, 18) (dual of [35, 8, 19]-code), but
- residual code [i] would yield linear OA(39, 16, F3, 6) (dual of [16, 7, 7]-code), but
- “vE2†bound on codes from Brouwer’s database [i]
- residual code [i] would yield linear OA(39, 16, F3, 6) (dual of [16, 7, 7]-code), but
- linear OA(319, 47, F3, 12) (dual of [47, 28, 13]-code), but
- discarding factors / shortening the dual code would yield linear OA(319, 46, F3, 12) (dual of [46, 27, 13]-code), but
- residual code [i] would yield OA(37, 33, S3, 4), but
- the linear programming bound shows that M ≥ 64125 / 28 > 37 [i]
- residual code [i] would yield OA(37, 33, S3, 4), but
- discarding factors / shortening the dual code would yield linear OA(319, 46, F3, 12) (dual of [46, 27, 13]-code), but
- linear OA(327, 35, F3, 18) (dual of [35, 8, 19]-code), but
- construction Y1 [i] would yield
Mode: Bound (linear).
