# A new bound for the crossing number of wrapped butterflies

## TL;DR

This paper corrects and refines the upper bound on the crossing number of wrapped butterflies, providing a more accurate estimate than previous results.

## Contribution

It identifies and fixes an error in earlier bounds, offering a tighter bound for the crossing number of wrapped butterflies.

## Key findings

- Corrected the previous bound for wrapped butterflies
- Provided a more precise crossing number estimate
- Enhanced understanding of graph crossing numbers

## Abstract

We fix an error in the bound obtained in [13] for the crossing number of wrapped butterflies. The new bound finer than the one provided earlier.
