Information on Result #547881
There is no linear OA(4151, 185, F4, 112) (dual of [185, 34, 113]-code), because construction Y1 would yield
- linear OA(4150, 165, F4, 112) (dual of [165, 15, 113]-code), but
- construction Y1 [i] would yield
- linear OA(4149, 157, F4, 112) (dual of [157, 8, 113]-code), but
- construction Y1 [i] would yield
- linear OA(4148, 153, F4, 112) (dual of [153, 5, 113]-code), but
- residual code [i] would yield linear OA(436, 40, F4, 28) (dual of [40, 4, 29]-code), but
- residual code [i] would yield linear OA(48, 11, F4, 7) (dual of [11, 3, 8]-code), but
- residual code [i] would yield linear OA(436, 40, F4, 28) (dual of [40, 4, 29]-code), but
- OA(48, 157, S4, 4), but
- discarding factors would yield OA(48, 121, S4, 4), but
- the Rao or (dual) Hamming bound shows that M ≥ 65704 > 48 [i]
- discarding factors would yield OA(48, 121, S4, 4), but
- linear OA(4148, 153, F4, 112) (dual of [153, 5, 113]-code), but
- construction Y1 [i] would yield
- OA(415, 165, S4, 8), but
- discarding factors would yield OA(415, 135, S4, 8), but
- the Rao or (dual) Hamming bound shows that M ≥ 1082 768311 > 415 [i]
- discarding factors would yield OA(415, 135, S4, 8), but
- linear OA(4149, 157, F4, 112) (dual of [157, 8, 113]-code), but
- construction Y1 [i] would yield
- OA(434, 185, S4, 20), but
- discarding factors would yield OA(434, 173, S4, 20), but
- the Rao or (dual) Hamming bound shows that M ≥ 305 996090 287239 486286 > 434 [i]
- discarding factors would yield OA(434, 173, S4, 20), but
Mode: Bound (linear).
