Information on Result #2158108
There is no linear OA(2244, 254, F2, 125) (dual of [254, 10, 126]-code), because 3 times truncation would yield linear OA(2241, 251, F2, 122) (dual of [251, 10, 123]-code), but
- residual code [i] would yield linear OA(2119, 128, F2, 61) (dual of [128, 9, 62]-code), but
- 1 times truncation [i] would yield linear OA(2118, 127, F2, 60) (dual of [127, 9, 61]-code), but
- residual code [i] would yield linear OA(258, 66, F2, 30) (dual of [66, 8, 31]-code), but
- adding a parity check bit [i] would yield linear OA(259, 67, F2, 31) (dual of [67, 8, 32]-code), but
- “DHM†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(259, 67, F2, 31) (dual of [67, 8, 32]-code), but
- residual code [i] would yield linear OA(258, 66, F2, 30) (dual of [66, 8, 31]-code), but
- 1 times truncation [i] would yield linear OA(2118, 127, F2, 60) (dual of [127, 9, 61]-code), but
Mode: Bound (linear).
