Question: Code stops after 2 lines of output.

I need help please. This is Maple 2019. I want to run through all possible bipartite tournaments with exactly 4 vertices in each partite set, and for each bipartite tournament compute the number of pair of vertices which has at least one common out-neighbor. 
1) The following code stops after two lines of output. Please advise how the code can be fixed.  
2) The printing of the adjaceny matrix using WeighMatrix(G) seems wrong too.

Thank you very much.😭😭

Please Wait...
