<｜begin▁of▁sentence｜>### Instruction:
You recently received a dataset containing the network of American college football teams, imported from a GML file named "football.gml." You are exploring methods for community detection in this network and have come across the union of all maximum spanning trees overlapping community detection algorithm (umstmo) in the cdlib library. You're looking to utilize this algorithm to identify communities within the football network and need a JSON representation of the identified communities. Can you demonstrate how to use the umstmo algorithm for community detection and provide a JSON representation of the communities identified in the American college football network?
### Response:
from cdlib import algorithms
import networkx as nx

G = nx.read_gml('football.gml')
communities = algorithms.umstmo(G)
print(communities.to_json())
