Information on Result #579917
There is no linear OOA(2181, 175, F2, 4, 99) (dual of [(175, 4), 519, 100]-NRT-code), because 2 times depth reduction would yield linear OOA(2181, 175, F2, 2, 99) (dual of [(175, 2), 169, 100]-NRT-code), but
- 15 step m-reduction [i] would yield linear OA(2166, 175, F2, 84) (dual of [175, 9, 85]-code), but
- residual code [i] would yield linear OA(282, 90, F2, 42) (dual of [90, 8, 43]-code), but
- adding a parity check bit [i] would yield linear OA(283, 91, F2, 43) (dual of [91, 8, 44]-code), but
- “DMa†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(283, 91, F2, 43) (dual of [91, 8, 44]-code), but
- residual code [i] would yield linear OA(282, 90, F2, 42) (dual of [90, 8, 43]-code), but
Mode: Bound (linear).
