Evaluate significance of triangles

This is a project to improve an already written MS Access script that find triangles, where the three edges of the triangle are contained in three separate files. The three files contain many edges, and the script searches for triangles that are formed by connecting edges, one from each file. Now, the script needs to randomly sample edges, and establish how many triangles are formed from each permutation. The script should randomly pull edges from a table. The interface should include: the number of permutations to be performed, and the number of samples to pull for file 1, file 2 and file 3.
