Information on Result #1288020
Linear OA(297, 116, F2, 42) (dual of [116, 19, 43]-code), using construction Y1 based on
- linear OA(298, 127, F2, 42) (dual of [127, 29, 43]-code), using
- the primitive narrow-sense BCH-code C(I) with length 127 = 27−1, defining interval I = [1,42], and designed minimum distance d ≥ |I|+1 = 43 [i]
- nonexistence of OA(229, 127, S2, 11), because
- discarding factors would yield OA(229, 126, S2, 11), but
- 1 times truncation [i] would yield OA(228, 125, S2, 10), but
- the linear programming bound shows that M ≥ 97 970049 515520 / 363679 > 228 [i]
- 1 times truncation [i] would yield OA(228, 125, S2, 10), but
- discarding factors would yield OA(229, 126, S2, 11), but
