Hi guys, there's one more thing Im stuck with. Suppose I have these points=(a,b,c,d);

Then I want to find the set of triplets induced by these 4 vertices.

For example for above four points the induced triplets should be:

b c a
a c d

Whereas for vertices=(d,e,a) there isn't any triplet in the data.
