Information on Result #2171173
There is no linear OA(919, 39, F9, 17) (dual of [39, 20, 18]-code), because 1 times truncation would yield linear OA(918, 38, F9, 16) (dual of [38, 20, 17]-code), but
- construction Y1 [i] would yield
- linear OA(917, 20, F9, 16) (dual of [20, 3, 17]-code), but
- linear OA(920, 38, F9, 18) (dual of [38, 18, 19]-code), but
- discarding factors / shortening the dual code would yield linear OA(920, 30, F9, 18) (dual of [30, 10, 19]-code), but
- residual code [i] would yield OA(92, 11, S9, 2), but
- bound for OAs with strength k = 2 [i]
- the Rao or (dual) Hamming bound shows that M ≥ 89 > 92 [i]
- residual code [i] would yield OA(92, 11, S9, 2), but
- discarding factors / shortening the dual code would yield linear OA(920, 30, F9, 18) (dual of [30, 10, 19]-code), but
Mode: Bound (linear).
