### How to use
Download the python file, navigate to its location and run it like this:

`python3 polygon_packer.py [n] [nsi] [nsc]`
`python3 polygon_packer.py -n [n] -nsi [nsi] -nsc [nsc]`
- Replace `[n]` with the number of inner polygons you want to solve for
- Replace `[nsi]` with the number of sides of the inner polygons (e.g. 4 for a square)
- Replace `[nsc]` with the number of sides of the container polygon
