Information on Result #2165172
There is no linear OA(4247, 254, F4, 187) (dual of [254, 7, 188]-code), because 3 times truncation would yield linear OA(4244, 251, F4, 184) (dual of [251, 7, 185]-code), but
- residual code [i] would yield OA(460, 66, S4, 46), but
- the linear programming bound shows that M ≥ 340 282366 920938 463463 374607 431768 211456 / 235 > 460 [i]
Mode: Bound (linear).
