Information on Result #2156832
There is no linear OA(2133, 186, F2, 63) (dual of [186, 53, 64]-code), because 1 times truncation would yield linear OA(2132, 185, F2, 62) (dual of [185, 53, 63]-code), but
- construction Y1 [i] would yield
- linear OA(2131, 165, F2, 62) (dual of [165, 34, 63]-code), but
- construction Y1 [i] would yield
- linear OA(2130, 153, F2, 62) (dual of [153, 23, 63]-code), but
- adding a parity check bit [i] would yield linear OA(2131, 154, F2, 63) (dual of [154, 23, 64]-code), but
- OA(234, 165, S2, 12), but
- discarding factors would yield OA(234, 154, S2, 12), but
- the Rao or (dual) Hamming bound shows that M ≥ 17486 314616 > 234 [i]
- discarding factors would yield OA(234, 154, S2, 12), but
- linear OA(2130, 153, F2, 62) (dual of [153, 23, 63]-code), but
- construction Y1 [i] would yield
- OA(253, 185, S2, 20), but
- discarding factors would yield OA(253, 182, S2, 20), but
- the Rao or (dual) Hamming bound shows that M ≥ 9064 436853 738748 > 253 [i]
- discarding factors would yield OA(253, 182, S2, 20), but
- linear OA(2131, 165, F2, 62) (dual of [165, 34, 63]-code), but
Mode: Bound (linear).
