I have a matrix (each row represents a traingle and each element represents a vertex ID of that traingle), I want to find which two traingles have two same vertices. This question can be demonstrated by the following example, for a matrix like the following:
1 9 8
2 7 8
5 8 9
6 5 4
7 3 8
5 4 8
the output would be [1, 3], [2, 5], and [3, 6], which are the rows have two same elements.

Use edges to get a list of all the edges of the triangulation. Then loop over the list and use edgeAttachments.
