<｜begin▁of▁sentence｜>### Instruction:
Given a NetworkX graph created using `nx.cubical_graph()` and a set of nodes `S = {0, 1, 2, 3}`, what is the node expansion of set S in the graph?
### Response:
import networkx as nx

# Create a graph
G = nx.cubical_graph()

# Define a set S of nodes to find the node expansion of
S = {0, 1, 2, 3}

# Calculate the node expansion
expansion = nx.node_expansion(G, S)

print('Node Expansion:', expansion)
