# Nontrivial example of the composition of the brane product and coproduct on Gorenstein spaces

## TL;DR

This paper presents a specific example of a Gorenstein space where the composition of the brane product and coproduct, previously introduced, is nontrivial, illustrating complex algebraic structures in topology.

## Contribution

It provides the first explicit example demonstrating the nontrivial composition of brane product and coproduct on Gorenstein spaces.

## Key findings

- Example of a Gorenstein space with nontrivial composition
- Illustration of complex algebraic structures in topology
- Validation of the theoretical framework for brane operations

## Abstract

We give an example of a space with the nontrivial composition of the brane product and the brane coproduct, which we introduced in a previous article.
