<｜begin▁of▁sentence｜>### Instruction:
Given a small directed graph with edges [(0, 1), (1, 2), (2, 0)], can you use the isoclass function to determine its isomorphism class?
### Response:
from igraph import Graph

# Define a small graph
g = Graph(edges=[(0, 1), (1, 2), (2, 0)], directed=True)

# Calculate the isomorphism class of the entire graph
iso_class = g.isoclass()

print('Isomorphism class:', iso_class)
