Information on Result #2174743
There is no linear OA(2145, 173, F2, 70) (dual of [173, 28, 71]-code), because 3 times code embedding in larger space would yield linear OA(2148, 176, F2, 70) (dual of [176, 28, 71]-code), but
- adding a parity check bit [i] would yield linear OA(2149, 177, F2, 71) (dual of [177, 28, 72]-code), but
Mode: Bound (linear).
