Information on Result #546321
There is no linear OA(2172, 221, F2, 82) (dual of [221, 49, 83]-code), because residual code would yield OA(290, 138, S2, 41), but
- 1 times truncation [i] would yield OA(289, 137, S2, 40), but
- the linear programming bound shows that M ≥ 94 055793 389946 937848 891499 500557 263777 562624 / 137978 313328 366875 > 289 [i]
Mode: Bound (linear).
