Information on Result #3149654
There is no digital (60, 243, 252)-net over F4, because 3 times m-reduction would yield digital (60, 240, 252)-net over F4, but
- extracting embedded orthogonal array [i] would yield linear OA(4240, 252, F4, 180) (dual of [252, 12, 181]-code), but
- construction Y1 [i] would yield
- linear OA(4239, 246, F4, 180) (dual of [246, 7, 181]-code), but
- residual code [i] 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
- 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(459, 65, F4, 45) (dual of [65, 6, 46]-code), but
- OA(412, 252, S4, 6), but
- discarding factors would yield OA(412, 156, S4, 6), but
- the Rao or (dual) Hamming bound shows that M ≥ 16 866019 > 412 [i]
- discarding factors would yield OA(412, 156, S4, 6), but
- linear OA(4239, 246, F4, 180) (dual of [246, 7, 181]-code), but
- construction Y1 [i] would yield
Mode: Bound (linear).
