Information on Result #560377
There is no linear OOA(4196, 226, F4, 2, 146) (dual of [(226, 2), 256, 147]-NRT-code), because 2 step m-reduction would yield linear OA(4194, 226, F4, 144) (dual of [226, 32, 145]-code), but
- construction Y1 [i] would yield
- linear OA(4193, 208, F4, 144) (dual of [208, 15, 145]-code), but
- construction Y1 [i] would yield
- linear OA(4192, 200, F4, 144) (dual of [200, 8, 145]-code), but
- construction Y1 [i] would yield
- linear OA(4191, 196, F4, 144) (dual of [196, 5, 145]-code), but
- residual code [i] would yield linear OA(447, 51, F4, 36) (dual of [51, 4, 37]-code), but
- OA(48, 200, 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(4191, 196, F4, 144) (dual of [196, 5, 145]-code), but
- construction Y1 [i] would yield
- OA(415, 208, 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(4192, 200, F4, 144) (dual of [200, 8, 145]-code), but
- construction Y1 [i] would yield
- OA(432, 226, S4, 18), but
- discarding factors would yield OA(432, 195, S4, 18), but
- the Rao or (dual) Hamming bound shows that M ≥ 18 632959 071185 877328 > 432 [i]
- discarding factors would yield OA(432, 195, S4, 18), but
- linear OA(4193, 208, F4, 144) (dual of [208, 15, 145]-code), but
Mode: Bound (linear).
