Information on Result #548067
There is no linear OA(397, 224, F3, 59) (dual of [224, 127, 60]-code), because construction Y1 would yield
- OA(396, 144, S3, 59), but
- the linear programming bound shows that M ≥ 2236 401438 247250 718182 900374 183456 399210 453427 110900 255699 874712 354347 141530 819695 / 326304 173287 366006 276464 537104 634223 > 396 [i]
- linear OA(3127, 224, F3, 80) (dual of [224, 97, 81]-code), but
- discarding factors / shortening the dual code would yield linear OA(3127, 178, F3, 80) (dual of [178, 51, 81]-code), but
- construction Y1 [i] would yield
- OA(3126, 150, S3, 80), but
- the linear programming bound shows that M ≥ 1 744284 668385 163500 346306 269658 104769 929699 691581 439318 970712 105752 702784 / 1 186440 433087 > 3126 [i]
- OA(351, 178, S3, 28), but
- discarding factors would yield OA(351, 172, S3, 28), but
- the Rao or (dual) Hamming bound shows that M ≥ 2 263924 665338 043697 613937 > 351 [i]
- discarding factors would yield OA(351, 172, S3, 28), but
- OA(3126, 150, S3, 80), but
- construction Y1 [i] would yield
- discarding factors / shortening the dual code would yield linear OA(3127, 178, F3, 80) (dual of [178, 51, 81]-code), but
Mode: Bound (linear).
