Information on Result #573160
There is no linear OOA(4107, 231, F4, 3, 75) (dual of [(231, 3), 586, 76]-NRT-code), because 2 times depth reduction would yield linear OA(4107, 231, F4, 75) (dual of [231, 124, 76]-code), but
- construction Y1 [i] would yield
- OA(4106, 143, S4, 75), but
- the linear programming bound shows that M ≥ 189 312298 968815 860250 485793 283965 413843 284713 743252 821000 560707 597443 674955 116200 018233 524224 / 27631 043169 340831 430975 152245 > 4106 [i]
- linear OA(4124, 231, F4, 88) (dual of [231, 107, 89]-code), but
- discarding factors / shortening the dual code would yield linear OA(4124, 210, F4, 88) (dual of [210, 86, 89]-code), but
- construction Y1 [i] would yield
- OA(4123, 150, S4, 88), but
- the linear programming bound shows that M ≥ 22915 666113 439092 609099 444232 414491 754857 959622 104295 992957 494311 648680 329878 580928 609806 974976 / 136 168406 561048 662801 > 4123 [i]
- OA(486, 210, S4, 60), but
- discarding factors would yield OA(486, 145, S4, 60), but

- discarding factors would yield OA(486, 145, S4, 60), but
- OA(4123, 150, S4, 88), but
- construction Y1 [i] would yield
- discarding factors / shortening the dual code would yield linear OA(4124, 210, F4, 88) (dual of [210, 86, 89]-code), but
- OA(4106, 143, S4, 75), but
