Information on Result #2156615
There is no linear OA(2107, 172, F2, 49) (dual of [172, 65, 50]-code), because 1 times truncation would yield linear OA(2106, 171, F2, 48) (dual of [171, 65, 49]-code), but
- construction Y1 [i] would yield
- OA(2105, 145, S2, 48), but
- the linear programming bound shows that M ≥ 727 070369 678229 731686 401086 929362 121333 407744 / 17 521374 765895 > 2105 [i]
- OA(265, 171, S2, 26), but
- discarding factors would yield OA(265, 170, S2, 26), but
- the linear programming bound shows that M ≥ 15890 939443 762705 189763 180081 227518 381108 756480 / 413 412834 411090 648392 969149 > 265 [i]
- discarding factors would yield OA(265, 170, S2, 26), but
- OA(2105, 145, S2, 48), but
Mode: Bound (linear).
