Information on Result #579353
There is no linear OOA(2147, 174, F2, 4, 71) (dual of [(174, 4), 549, 72]-NRT-code), because 2 times depth reduction would yield linear OOA(2147, 174, F2, 2, 71) (dual of [(174, 2), 201, 72]-NRT-code), but
- 1 step m-reduction [i] would yield linear OA(2146, 174, F2, 70) (dual of [174, 28, 71]-code), but
- 2 times code embedding in larger space [i] 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
- 2 times code embedding in larger space [i] would yield linear OA(2148, 176, F2, 70) (dual of [176, 28, 71]-code), but
Mode: Bound (linear).
