Information on Result #582944
There is no linear OOA(3181, 171, F3, 4, 127) (dual of [(171, 4), 503, 128]-NRT-code), because 2 times depth reduction would yield linear OOA(3181, 171, F3, 2, 127) (dual of [(171, 2), 161, 128]-NRT-code), but
- 19 step m-reduction [i] would yield linear OA(3162, 171, F3, 108) (dual of [171, 9, 109]-code), but
- construction Y1 [i] would yield
- linear OA(3161, 167, F3, 108) (dual of [167, 6, 109]-code), but
- residual code [i] would yield linear OA(353, 58, F3, 36) (dual of [58, 5, 37]-code), but
- residual code [i] would yield linear OA(317, 21, F3, 12) (dual of [21, 4, 13]-code), but
- residual code [i] would yield linear OA(353, 58, F3, 36) (dual of [58, 5, 37]-code), but
- OA(39, 171, S3, 4), but
- discarding factors would yield OA(39, 100, S3, 4), but
- the Rao or (dual) Hamming bound shows that M ≥ 20001 > 39 [i]
- discarding factors would yield OA(39, 100, S3, 4), but
- linear OA(3161, 167, F3, 108) (dual of [167, 6, 109]-code), but
- construction Y1 [i] would yield
Mode: Bound (linear).
