<｜begin▁of▁sentence｜>### Instruction:
Given an undirected graph with edges [(0, 1), (1, 2), (2, 3), (3, 0)], can you determine the isomorphism class of the graph or its subgraph using the isoclass function in igraph?
### Response:
from igraph import Graph

# Create a graph with 4 vertices
edges = [(0, 1), (1, 2), (2, 3), (3, 0)]
g = Graph(edges=edges, directed=False)

# Get the isomorphism class of the graph or its subgraph
iso_class = g.isoclass()

# Print the isomorphism class
print('Isomorphism class of the graph:', iso_class)
