Information on Result #2156880
There is no linear OA(2139, 186, F2, 67) (dual of [186, 47, 68]-code), because 1 times truncation would yield linear OA(2138, 185, F2, 66) (dual of [185, 47, 67]-code), but
- residual code [i] would yield OA(272, 118, S2, 33), but
- 1 times truncation [i] would yield OA(271, 117, S2, 32), but
- the linear programming bound shows that M ≥ 436299 229870 540803 344540 378506 426337 722368 / 173 222223 038567 257555 > 271 [i]
- 1 times truncation [i] would yield OA(271, 117, S2, 32), but
Mode: Bound (linear).
