Information on Result #580512
There is no linear OOA(2225, 217, F2, 4, 122) (dual of [(217, 4), 643, 123]-NRT-code), because 2 times depth reduction would yield linear OOA(2225, 217, F2, 2, 122) (dual of [(217, 2), 209, 123]-NRT-code), but
- 18 step m-reduction [i] would yield linear OA(2207, 217, F2, 104) (dual of [217, 10, 105]-code), but
- residual code [i] would yield linear OA(2103, 112, F2, 52) (dual of [112, 9, 53]-code), but
- residual code [i] would yield linear OA(251, 59, F2, 26) (dual of [59, 8, 27]-code), but
- adding a parity check bit [i] would yield linear OA(252, 60, F2, 27) (dual of [60, 8, 28]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(252, 60, F2, 27) (dual of [60, 8, 28]-code), but
- residual code [i] would yield linear OA(251, 59, F2, 26) (dual of [59, 8, 27]-code), but
- residual code [i] would yield linear OA(2103, 112, F2, 52) (dual of [112, 9, 53]-code), but
Mode: Bound (linear).
