<｜begin▁of▁sentence｜>### Instruction:
Imagine you're in the heart of a bustling glassblowing studio, surrounded by the warmth of the furnaces and the vibrant colors of molten glass being sculpted into exquisite forms. In this creative sanctuary, the master glassblower is faced with a new challenge - crafting a series of interconnected glass sculptures that embody the essence of unity and distinction. To achieve this, the glassblower decides to map out the relationships between different elements of the project as an undirected graph, using pairs of connections which include (1, 2), (1, 3), (2, 3), (3, 4), (4, 5), (4, 6), and (5, 6).

To bring this vision to life, the glassblower seeks to identify two crucial structural arrangements. The first is to discover the largest group of elements that can be fused together in perfect harmony without any of them clashing - a representation of the largest clique within this network. The second is to determine the most significant number of elements that can stand independently, embodying their unique beauty without direct connection to others - akin to the largest independent set.

In seeking the essence of balance and cooperation among the elements, the glassblower turns to the traditional techniques of network analysis, pondering the use of the ramsey_r2 function from NetworkX as a tool to uncover these arrangements. This approach promises to illuminate the path towards creating a masterpiece that embodies both closeness and independence, reflecting the core principles of glassblowing art. How can the ramsey_r2 function be utilized in this artistic endeavor to identify the largest clique and the largest independent set within the interconnected web of glass sculptures?
### Response:
import networkx as nx

# Create an undirected graph
G = nx.Graph()

# Add some edges
G.add_edges_from([(1, 2), (1, 3), (2, 3), (3, 4), (4, 5), (4, 6), (5, 6)])

# Compute the largest clique and largest independent set
max_clique, max_independent_set = nx.algorithms.approximation.ramsey.ramsey_r2(G)

print('Maximum clique:', max_clique)
print('Maximum independent set:', max_independent_set)
<|EOT|>
