Information on Result #2164030
There is no linear OA(4144, 166, F4, 107) (dual of [166, 22, 108]-code), because 3 times truncation would yield linear OA(4141, 163, F4, 104) (dual of [163, 22, 105]-code), but
- construction Y1 [i] would yield
- OA(4140, 151, S4, 104), but
- 2 times truncation [i] would yield OA(4138, 149, S4, 102), but
- the linear programming bound shows that M ≥ 11 769278 720446 703333 267659 747956 551886 187319 922656 933070 157940 129170 842786 675855 465333 653504 / 85 907459 > 4138 [i]
- 2 times truncation [i] would yield OA(4138, 149, S4, 102), but
- OA(422, 163, S4, 12), but
- the linear programming bound shows that M ≥ 22822 886502 605724 057600 / 1273 153051 > 422 [i]
- OA(4140, 151, S4, 104), but
Mode: Bound (linear).
