The gyroid is a triply periodic minimal surface the fundamental patch of which is reproduced opposite.

The two figures are based on the equation  that gives a non-minimal surface close to the true gyroid.
 

The fundamental patch is composed of 8 isometric skew hexagons, six of which have a vertex at the center of the patch.
The complete gyroid separates the space into two isometric domains, like the Schwarz P surface.

Compare to the Neovius surface.
