Information on Result #1288004
Linear OA(239, 155, F2, 10) (dual of [155, 116, 11]-code), using construction Y1 based on
- linear OA(240, 255, F2, 10) (dual of [255, 215, 11]-code), using
- the primitive narrow-sense BCH-code C(I) with length 255 = 28−1, defining interval I = [1,10], and designed minimum distance d ≥ |I|+1 = 11 [i]
- nonexistence of OA(2215, 255, S2, 100), because
- discarding factors would yield OA(2215, 251, S2, 100), but
- the linear programming bound shows that M ≥ 257049 453189 140945 613695 781062 476077 678522 037899 401039 162840 762880 750568 603648 / 4 012062 840109 > 2215 [i]
- discarding factors would yield OA(2215, 251, S2, 100), but
