Information on Result #547885
There is no linear OA(4159, 167, F4, 120) (dual of [167, 8, 121]-code), because construction Y1 would yield
- linear OA(4158, 163, F4, 120) (dual of [163, 5, 121]-code), but
- residual code [i] would yield linear OA(438, 42, F4, 30) (dual of [42, 4, 31]-code), but
- 2 times truncation [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
- 2 times truncation [i] would yield linear OA(436, 40, F4, 28) (dual of [40, 4, 29]-code), but
- residual code [i] would yield linear OA(438, 42, F4, 30) (dual of [42, 4, 31]-code), but
- OA(48, 167, 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).
