<｜begin▁of▁sentence｜>### Instruction:
As a truck driver, you navigate trucks across various routes, ensuring timely delivery and compliance with safety regulations. Imagine you're tasked with determining the most efficient route for transporting goods between different locations. Your task involves analyzing the road network, represented as a graph, with specific connections between locations. To optimize the route, you need to understand the symmetries and automorphisms within this network. One way to do this is by utilizing a tool like the count_automorphisms function in the igraph API. This function helps identify the number of automorphisms in the graph, providing insights into symmetrical patterns and potential redundancies in the route, ultimately aiding in efficient transportation planning and logistics management.
### Response:
from igraph import Graph

# Define a simple graph
edges = [(0, 1), (0, 2), (1, 2), (1, 3)]
g = Graph(edges=edges)

# Count the number of automorphisms
num_automorphisms = g.count_automorphisms()

print('The number of automorphisms is:', num_automorphisms)
