Information on Result #2169596
There is no linear OA(829, 77, F8, 25) (dual of [77, 48, 26]-code), because 1 times truncation would yield linear OA(828, 76, F8, 24) (dual of [76, 48, 25]-code), but
- construction Y1 [i] would yield
- linear OA(827, 34, F8, 24) (dual of [34, 7, 25]-code), but
- construction Y1 [i] would yield
- OA(826, 28, S8, 24), but
- the (dual) Plotkin bound shows that M ≥ 9 671406 556917 033397 649408 / 25 > 826 [i]
- OA(87, 34, S8, 6), but
- discarding factors would yield OA(87, 32, S8, 6), but
- the linear programming bound shows that M ≥ 3784 900608 / 1729 > 87 [i]
- discarding factors would yield OA(87, 32, S8, 6), but
- OA(826, 28, S8, 24), but
- construction Y1 [i] would yield
- linear OA(848, 76, F8, 42) (dual of [76, 28, 43]-code), but
- discarding factors / shortening the dual code would yield linear OA(848, 58, F8, 42) (dual of [58, 10, 43]-code), but
- construction Y1 [i] would yield
- linear OA(847, 50, F8, 42) (dual of [50, 3, 43]-code), but
- “Hi4†bound on codes from Brouwer’s database [i]
- OA(810, 58, S8, 8), but
- discarding factors would yield OA(810, 57, S8, 8), but
- the linear programming bound shows that M ≥ 1426 626655 027200 / 1 315507 > 810 [i]
- discarding factors would yield OA(810, 57, S8, 8), but
- linear OA(847, 50, F8, 42) (dual of [50, 3, 43]-code), but
- construction Y1 [i] would yield
- discarding factors / shortening the dual code would yield linear OA(848, 58, F8, 42) (dual of [58, 10, 43]-code), but
- linear OA(827, 34, F8, 24) (dual of [34, 7, 25]-code), but
Mode: Bound (linear).
