Information on Result #2157028
There is no linear OA(2147, 215, F2, 69) (dual of [215, 68, 70]-code), because 1 times truncation would yield linear OA(2146, 214, F2, 68) (dual of [214, 68, 69]-code), but
- residual code [i] would yield OA(278, 145, S2, 34), but
- the linear programming bound shows that M ≥ 6 452658 897421 925882 991923 762933 214377 859980 440698 591468 415644 336128 / 20 712793 240469 221474 764436 259197 787149 263939 > 278 [i]
