Information on Result #563139
There is no linear OOA(833, 46, F8, 2, 29) (dual of [(46, 2), 59, 30]-NRT-code), because 1 step m-reduction would yield linear OA(832, 46, F8, 28) (dual of [46, 14, 29]-code), but
- construction Y1 [i] would yield
- linear OA(831, 34, F8, 28) (dual of [34, 3, 29]-code), but
- “Mas†bound on codes from Brouwer’s database [i]
- linear OA(814, 46, F8, 12) (dual of [46, 32, 13]-code), but
- discarding factors / shortening the dual code would yield linear OA(814, 32, F8, 12) (dual of [32, 18, 13]-code), but
- construction Y1 [i] would yield
- linear OA(813, 16, F8, 12) (dual of [16, 3, 13]-code), but
- “Hi4†bound on codes from Brouwer’s database [i]
- linear OA(818, 32, F8, 16) (dual of [32, 14, 17]-code), but
- discarding factors / shortening the dual code would yield linear OA(818, 27, F8, 16) (dual of [27, 9, 17]-code), but
- residual code [i] would yield OA(82, 10, S8, 2), but
- bound for OAs with strength k = 2 [i]
- the Rao or (dual) Hamming bound shows that M ≥ 71 > 82 [i]
- residual code [i] would yield OA(82, 10, S8, 2), but
- discarding factors / shortening the dual code would yield linear OA(818, 27, F8, 16) (dual of [27, 9, 17]-code), but
- linear OA(813, 16, F8, 12) (dual of [16, 3, 13]-code), but
- construction Y1 [i] would yield
- discarding factors / shortening the dual code would yield linear OA(814, 32, F8, 12) (dual of [32, 18, 13]-code), but
- linear OA(831, 34, F8, 28) (dual of [34, 3, 29]-code), but
Mode: Bound (linear).
