<｜begin▁of▁sentence｜>### Instruction:
Suppose we're investigating the linguistic diversity of sentence structures that can be generated using a finite number of grammatical elements, parallel to examining the structural variety of arboreal diagrams in the realm of graph theory. If we consider an "order" to represent the total elements available to us—akin to words or syntactic units in a sentence—our task is to determine the number of unique syntactic trees, each constituting a distinct sentence structure, without any repetitive patterns.

More precisely, let's say we have an "order" of 4, analogous to four words or syntax units at our disposal, and we wish to calculate how many syntactically unique sentence trees can be crafted, ensuring that no two trees can be mirrored, rotated, or rearranged to resemble one another in their structural conformation.

In this case, using the NetworkX library as our computational tool—much like employing a corpus analysis software in linguistics—how might we compute the count of nonisomorphic sentence trees corresponding to this specific order?
### Response:
import networkx as nx

# Calculate the number of nonisomorphic trees for a given order
order = 4
num_trees = nx.number_of_nonisomorphic_trees(order)

print(f'Number of nonisomorphic trees of order {order}:', num_trees)
