• Not thinking about this one right

Hey! Quick question about the combinatorics in Fix The Generator. Now you say that a triangle is a triangle in this case when a + b = c. I'm slightly confused when you get above three integers, like in the example [5, 2, 9, 6]. Now [5, 2, 9] and [2, 9, 6] don't make triangles in any combination, but what about [5, 2, 6]? Why didn't this combination merit mention? Let me know. Thanks!
