Information on Result #2164287
There is no linear OA(4174, 196, F4, 130) (dual of [196, 22, 131]-code), because 2 times truncation would yield linear OA(4172, 194, F4, 128) (dual of [194, 22, 129]-code), but
- construction Y1 [i] would yield
- linear OA(4171, 182, F4, 128) (dual of [182, 11, 129]-code), but
- construction Y1 [i] would yield
- linear OA(4170, 176, F4, 128) (dual of [176, 6, 129]-code), but
- construction Y1 [i] would yield
- linear OA(4169, 173, F4, 128) (dual of [173, 4, 129]-code), but
- linear OA(46, 176, F4, 3) (dual of [176, 170, 4]-code or 176-cap in PG(5,4)), but
- construction Y1 [i] would yield
- OA(411, 182, S4, 6), but
- discarding factors would yield OA(411, 99, S4, 6), but
- the Rao or (dual) Hamming bound shows that M ≥ 4 278880 > 411 [i]
- discarding factors would yield OA(411, 99, S4, 6), but
- linear OA(4170, 176, F4, 128) (dual of [176, 6, 129]-code), but
- construction Y1 [i] would yield
- OA(422, 194, S4, 12), but
- discarding factors would yield OA(422, 164, S4, 12), but
- the Rao or (dual) Hamming bound shows that M ≥ 18 187369 733464 > 422 [i]
- discarding factors would yield OA(422, 164, S4, 12), but
- linear OA(4171, 182, F4, 128) (dual of [182, 11, 129]-code), but
Mode: Bound (linear).
