Information on Result #547901
There is no linear OA(4188, 196, F4, 142) (dual of [196, 8, 143]-code), because construction Y1 would yield
- linear OA(4187, 192, F4, 142) (dual of [192, 5, 143]-code), but
- OA(48, 196, 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
Mode: Bound (linear).
