Summary

Description

A three-component link which is a Brunnian link (i.e. cutting any loop frees the other two loops), but which is not the same as the Borromean rings. For another three-component Brunnian link which is not the same as the Borromean rings, see Image:Three-triang-18crossings-Brunnian.png . For a visually more decorative and ornate version of this, see File:Brunnian-link-12crossings-nonBorromean-quasi-Arabesque.svg

A version of this was found in the ancient roman mosaics at Villa del Casale (Piazza Armerina) (see external link http://www.liv.ac.uk/%7Espmr02/rings/maths.html ).
