<｜begin▁of▁sentence｜>### Instruction:
Given a binary tree graph with 127 vertices, can you use the community_edge_betweenness function in igraph to perform community detection and then convert the resulting VertexDendrogram object to a string?
### Response:
import igraph as ig

# Assume a graph 'g' and a VertexDendrogram object 'dendrogram'
g = ig.Graph.Tree(127, 2)
dendrogram = g.community_edge_betweenness()
# Convert dendrogram to string representation
str_dendrogram = dendrogram.__str__()
print(str_dendrogram)
