<｜begin▁of▁sentence｜>### Instruction:
Suppose we're crafting a unique piece of jewelry inspired by the structure of the Petersen graph, a captivating design famed for its complexity and symmetry. We're interested in the intrinsic beauty of the shortest loop within this design, akin to the shortest necklace chain we could create while maintaining the graph's pattern.

To encapsulate this concept into our jewelry piece, could we determine the "girth" of the Petersen graph? This metric would represent the length of the most concise loop, or in our artistic interpretation, the smallest bracelet or ring that could be fashioned while respecting the Petersen graph's intricate connections. Should the graph's design not permit any loops, we would regard our creation as a series of unending chains, or in mathematical terms, the girth would be infinite.

In the absence of any loops, our design would possess a more linear character, whereas the discovery of a short loop could inspire a charming and interwoven aesthetic for our next jewelry masterpiece.
### Response:
import networkx as nx

# Create a graph (Petersen graph in this case)
G = nx.petersen_graph()

# Calculate the girth of the graph
graph_girth = nx.girth(G)

print('The girth of the Petersen graph is:', graph_girth)
<|EOT|>
