Lidinoid

In differential geometry, the lidinoid is a triply periodic minimal surface.

The name comes from its Swedish discoverer Sven Lidin (who called it the HG surface).

[1] It has many similarities to the gyroid, and just as the gyroid is the unique embedded member of the associate family of the Schwarz P surface the lidinoid is the unique embedded member of the associate family of a Schwarz H surface.

The Lidinoid can be approximated as a level set:[3]
