Information on Result #587132
There is no linear OOA(2238, 247, F2, 5, 121) (dual of [(247, 5), 997, 122]-NRT-code), because 3 times depth reduction would yield linear OOA(2238, 247, F2, 2, 121) (dual of [(247, 2), 256, 122]-NRT-code), but
- 1 step m-reduction [i] would yield linear OA(2237, 247, F2, 120) (dual of [247, 10, 121]-code), but
- residual code [i] would yield linear OA(2117, 126, F2, 60) (dual of [126, 9, 61]-code), but
- residual code [i] would yield linear OA(257, 65, F2, 30) (dual of [65, 8, 31]-code), but
- 2 times truncation [i] would yield linear OA(255, 63, F2, 28) (dual of [63, 8, 29]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- 2 times truncation [i] would yield linear OA(255, 63, F2, 28) (dual of [63, 8, 29]-code), but
- residual code [i] would yield linear OA(257, 65, F2, 30) (dual of [65, 8, 31]-code), but
- residual code [i] would yield linear OA(2117, 126, F2, 60) (dual of [126, 9, 61]-code), but
Mode: Bound (linear).
