<｜begin▁of▁sentence｜>### Instruction:
{'Description': 'Given an integer representing the order of trees, find out how many nonisomorphic trees exist for that order using NetworkX.', 'Parameters': {'order': 6}, 'Problem Solved': 'This code determines the number of distinct (nonisomorphic) trees that can be formed with 6 nodes.'}
### Response:
import networkx as nx

# Get the number of nonisomorphic trees of order 6
num_trees = nx.number_of_nonisomorphic_trees(6)
print(f'Number of nonisomorphic trees of order 6: {num_trees}')
