<｜begin▁of▁sentence｜>### Instruction:
Given a specific number of vertices and an isomorphism class for directed graphs of size 4, can you create a directed graph using the GraphBase.Isoclass function in igraph and display a summary of the generated graph?
### Response:
import igraph as ig

# Use GraphBase.Isoclass to generate a directed graph of size 4 with a given isomorphism class (for example, isomorphism class 3)
g = ig.GraphBase.Isoclass(n=4, cls=3, directed=True)

# Print out the summary of the graph
print(g.summary())
