Enumerate isomrphic subgraphs of graph vertex labeled

Enumerate all isomorphic subgraphs of given graph given the subgraph adjacency matrix

All graphs in Sage support iteration over its major subcomponents, at least vertices and to create a graph from its adjacency matrix

mg= Graph(adj) mg.is_isomorphic(mg) -> True

```
# graph from adjency matrix
adj= Matrix ([ [0, 1, 1], [1, 0, 1], [1, 1, 0] ])
mg= Graph(adj)
mg.is_isomorphic(mg) -> True
```

If are you looking for the isomorphic subgraphs of the one you specify with the adj. graph you can usemg.subgraph_search_iterator().

too see how it might be used here. If you post the source as suggested above we could get a more detailed answer.

Here is a simple example of looking for the simplest graph, with zero vertices:

```
eg = Graph()
[p for p in mg.subgraph_search_iterator(eg)]
```
