Information on Result #2164944
There is no linear OA(4228, 247, F4, 171) (dual of [247, 19, 172]-code), because 3 times truncation would yield linear OA(4225, 244, F4, 168) (dual of [244, 19, 169]-code), but
- residual code [i] would yield OA(457, 75, S4, 42), but
- the linear programming bound shows that M ≥ 175541 891167 451460 543215 010075 896682 965259 780096 / 6 746458 181029 > 457 [i]
Mode: Bound (linear).
