Information on Result #547728
There is no linear OA(2256, 282, F2, 126) (dual of [282, 26, 127]-code), because construction Y1 would yield
- linear OA(2255, 274, F2, 126) (dual of [274, 19, 127]-code), but
- residual code [i] would yield OA(2129, 147, S2, 63), but
- 1 times truncation [i] would yield OA(2128, 146, S2, 62), but
- the linear programming bound shows that M ≥ 10 546031 115613 724859 656905 833525 360409 444352 / 30229 > 2128 [i]
- 1 times truncation [i] would yield OA(2128, 146, S2, 62), but
- residual code [i] would yield OA(2129, 147, S2, 63), but
- OA(226, 282, S2, 8), but
- discarding factors would yield OA(226, 201, S2, 8), but
- the Rao or (dual) Hamming bound shows that M ≥ 67 351952 > 226 [i]
- discarding factors would yield OA(226, 201, S2, 8), but
Mode: Bound (linear).
