Information on Result #548509
There is no linear OA(4239, 246, F4, 180) (dual of [246, 7, 181]-code), because residual code would yield linear OA(459, 65, F4, 45) (dual of [65, 6, 46]-code), but
- 1 times truncation [i] would yield linear OA(458, 64, F4, 44) (dual of [64, 6, 45]-code), but
- residual code [i] would yield linear OA(414, 19, F4, 11) (dual of [19, 5, 12]-code), but
- 1 times truncation [i] would yield linear OA(413, 18, F4, 10) (dual of [18, 5, 11]-code), but
- “Liz†bound on codes from Brouwer’s database [i]
- 1 times truncation [i] would yield linear OA(413, 18, F4, 10) (dual of [18, 5, 11]-code), but
- residual code [i] would yield linear OA(414, 19, F4, 11) (dual of [19, 5, 12]-code), but
Mode: Bound (linear).
