Information on Result #578456
There is no linear OOA(28, 18, F2, 4, 4) (dual of [(18, 4), 64, 5]-NRT-code), because 3 times depth reduction would yield linear OA(28, 18, F2, 4) (dual of [18, 10, 5]-code), but
- construction Y1 [i] would yield
- linear OA(27, 12, F2, 4) (dual of [12, 5, 5]-code), but
- OA(210, 18, S2, 6), but
- discarding factors would yield OA(210, 16, S2, 6), but
- the linear programming bound shows that M ≥ 27136 / 21 > 210 [i]
- discarding factors would yield OA(210, 16, S2, 6), but
Mode: Bound (linear).
