Information on Result #2164144
There is no linear OA(4162, 174, F4, 122) (dual of [174, 12, 123]-code), because 2 times truncation would yield linear OA(4160, 172, F4, 120) (dual of [172, 12, 121]-code), but
- construction Y1 [i] would yield
- linear OA(4159, 166, F4, 120) (dual of [166, 7, 121]-code), but
- residual code [i] would yield linear OA(439, 45, F4, 30) (dual of [45, 6, 31]-code), but
- OA(412, 172, S4, 6), but
- discarding factors would yield OA(412, 156, S4, 6), but
- the Rao or (dual) Hamming bound shows that M ≥ 16 866019 > 412 [i]
- discarding factors would yield OA(412, 156, S4, 6), but
- linear OA(4159, 166, F4, 120) (dual of [166, 7, 121]-code), but
Mode: Bound (linear).
