Problem when using the index output of 3D Proximity to create a mesh

I am trying to use the index integers from the 3D Proximity Component to create mesh faces.  When I define the mesh faces with the given indexes, the algorithm structure I a using seems to be creating at least one face per set of three points.  I am want exactly one face per set of three points.  

I have attached a demonstration of what I'm talking about.  I use a few weaverbird components to show the problem clearly

I can think of two ways of solving this:

1. Find a way of defining the mesh faces which does not cause redundancies.

2. Delete redundant face definitions

a. i can check for redundancies in the sets of index integers used to define faces.  This could be easiest in that i would be comparing sets of numbers

b. i can check for redundancies in the set of face representations of the output. 

Any suggestions would be great. Thanks!!

Best
