<｜begin▁of▁sentence｜>### Instruction:
Imagine we're crafting a symphony of interconnected themes, represented by a cycle of 5 distinct musical phrases—each corresponding to a node in our metaphorical Cycle Graph Quintet. Now, let's consider blending the first two phrases (our nodes 0 and 1) into a single, harmonious motif, effectively merging their unique qualities. The artistic inquiry before us: Does this fusion give us a new Cycle Graph Quartet that maintains the cyclic integrity of the original composition? To explore this, let's compare the resulting arrangement to an existing Cycle Graph Quartet and confirm if they resonate with the same structural harmony. While conducting this experiment, there's no need to provide the practical steps of orchestration—simply ponder if the essence of the cycle will remain after the transformation.
### Response:
import networkx as nx

# Create an example cycle graph with 5 nodes
C5 = nx.cycle_graph(5)

# Contract the edge (0, 1)
M = nx.contracted_edge(C5, (0, 1), self_loops=False)

# Check if the result is isomorphic to a cycle graph with 4 nodes (since one edge was contracted)
C4 = nx.cycle_graph(4)
is_isomorphic = nx.is_isomorphic(M, C4)
print('Is M isomorphic to C4?', is_isomorphic)
