Information on Result #550223
There is no linear OOA(5121, 238, F5, 2, 92) (dual of [(238, 2), 355, 93]-NRT-code), because 1 times depth reduction would yield linear OA(5121, 238, F5, 92) (dual of [238, 117, 93]-code), but
- construction Y1 [i] would yield
- OA(5120, 149, S5, 92), but
- the linear programming bound shows that M ≥ 1875 115433 709844 937609 244603 657370 223629 726878 856922 329955 321895 357533 978909 714278 415776 789188 385009 765625 / 2299 458852 249280 370649 > 5120 [i]
- linear OA(5117, 238, F5, 89) (dual of [238, 121, 90]-code), but
- discarding factors / shortening the dual code would yield linear OA(5117, 226, F5, 89) (dual of [226, 109, 90]-code), but
- construction Y1 [i] would yield
- OA(5116, 143, S5, 89), but

- discarding factors / shortening the dual code would yield linear OA(5117, 226, F5, 89) (dual of [226, 109, 90]-code), but
