Information on Result #2160712
There is no linear OA(3177, 186, F3, 119) (dual of [186, 9, 120]-code), because 2 times truncation would yield linear OA(3175, 184, F3, 117) (dual of [184, 9, 118]-code), but
- construction Y1 [i] would yield
- linear OA(3174, 180, F3, 117) (dual of [180, 6, 118]-code), but
- residual code [i] would yield linear OA(357, 62, F3, 39) (dual of [62, 5, 40]-code), but
- residual code [i] would yield linear OA(318, 22, F3, 13) (dual of [22, 4, 14]-code), but
- 1 times truncation [i] would yield linear OA(317, 21, F3, 12) (dual of [21, 4, 13]-code), but
- residual code [i] would yield linear OA(318, 22, F3, 13) (dual of [22, 4, 14]-code), but
- residual code [i] would yield linear OA(357, 62, F3, 39) (dual of [62, 5, 40]-code), but
- OA(39, 184, 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(3174, 180, F3, 117) (dual of [180, 6, 118]-code), but
Mode: Bound (linear).
