Linux Mint is based on Ubuntu which is based on Debian. Also, Linux Mint offers a "Debian Edition": https://linuxmint.com/download_lmde.php
The download for their Debian Edition is hidden away under "other editions" as "LMDE". If you click on "recommended" you will get to the main download page which doesn't even mention the Debian Edition: https://linuxmint.com/download.php
Ok, good addition
