Information on Result #593686
There is no linear OOA(2246, 386, F2, 6, 110) (dual of [(386, 6), 2070, 111]-NRT-code), because 5 times depth reduction would yield linear OA(2246, 386, F2, 110) (dual of [386, 140, 111]-code), but
- construction Y1 [i] would yield
- linear OA(2245, 332, F2, 110) (dual of [332, 87, 111]-code), but
- construction Y1 [i] would yield
- OA(2244, 300, S2, 110), but
- the linear programming bound shows that M ≥ 727209 932038 995964 963694 786156 506719 769259 430085 807852 102717 045283 079365 167115 254635 995296 956416 / 21378 491075 472167 578125 > 2244 [i]
- OA(287, 332, S2, 32), but
- discarding factors would yield OA(287, 302, S2, 32), but
- the Rao or (dual) Hamming bound shows that M ≥ 161 699122 225452 699910 750634 > 287 [i]
- discarding factors would yield OA(287, 302, S2, 32), but
- OA(2244, 300, S2, 110), but
- construction Y1 [i] would yield
- linear OA(2140, 386, F2, 54) (dual of [386, 246, 55]-code), but
- discarding factors / shortening the dual code would yield linear OA(2140, 376, F2, 54) (dual of [376, 236, 55]-code), but
- the improved Johnson bound shows that N ≤ 638271 859848 635367 775356 676031 149307 988937 824926 330314 504342 114737 011555 < 2236 [i]
- discarding factors / shortening the dual code would yield linear OA(2140, 376, F2, 54) (dual of [376, 236, 55]-code), but
- linear OA(2245, 332, F2, 110) (dual of [332, 87, 111]-code), but
Mode: Bound (linear).
