Information on Result #594744
There is no linear OOA(2145, 137, F2, 7, 81) (dual of [(137, 7), 814, 82]-NRT-code), because 5 times depth reduction would yield linear OOA(2145, 137, F2, 2, 81) (dual of [(137, 2), 129, 82]-NRT-code), but
- 17 step m-reduction [i] would yield linear OA(2128, 137, F2, 64) (dual of [137, 9, 65]-code), but
- residual code [i] would yield linear OA(264, 72, F2, 32) (dual of [72, 8, 33]-code), but
- adding a parity check bit [i] would yield linear OA(265, 73, F2, 33) (dual of [73, 8, 34]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(265, 73, F2, 33) (dual of [73, 8, 34]-code), but
- residual code [i] would yield linear OA(264, 72, F2, 32) (dual of [72, 8, 33]-code), but
Mode: Bound (linear).
