Information on Result #1288039
Linear OA(3209, 227, F3, 120) (dual of [227, 18, 121]-code), using construction Y1 based on
- linear OA(3210, 242, F3, 120) (dual of [242, 32, 121]-code), using
- the primitive narrow-sense BCH-code C(I) with length 242 = 35−1, defining interval I = [1,120], and designed minimum distance d ≥ |I|+1 = 121 [i]
- nonexistence of OA(332, 242, S3, 15), because
- discarding factors would yield OA(332, 223, S3, 15), but
- 1 times truncation [i] would yield OA(331, 222, S3, 14), but
- the Rao or (dual) Hamming bound shows that M ≥ 623 503740 361401 > 331 [i]
- 1 times truncation [i] would yield OA(331, 222, S3, 14), but
- discarding factors would yield OA(332, 223, S3, 15), but
