Information on Result #599483
There is no digital (47, 186, 218)-net over F4, because extracting embedded orthogonal array would yield linear OA(4186, 218, F4, 139) (dual of [218, 32, 140]-code), but
- construction Y1 [i] would yield
- linear OA(4185, 200, F4, 139) (dual of [200, 15, 140]-code), but
- construction Y1 [i] would yield
- linear OA(4184, 192, F4, 139) (dual of [192, 8, 140]-code), but
- construction Y1 [i] would yield
- linear OA(4183, 188, F4, 139) (dual of [188, 5, 140]-code), but
- OA(48, 192, 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
- construction Y1 [i] would yield
- OA(415, 200, 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(4184, 192, F4, 139) (dual of [192, 8, 140]-code), but
- construction Y1 [i] would yield
- OA(432, 218, 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(4185, 200, F4, 139) (dual of [200, 15, 140]-code), but
Mode: Bound (linear).
