The quarter cubic honeycomb (or bitruncated alternated cubic honeycomb) is a space-filling tessellation (or honeycomb) in Euclidean 3-space. It is composed of tetrahedra and truncated tetrahedra in a ratio of 1:1. It is called "quarter-cubic" because its symmetry unit – the minimal block from which the pattern is developed by reflections – consists of four such units of the cubic honeycomb.
It is vertex-transitive with 6 truncated tetrahedra and 2 tetrahedra around each vertex.
It is one of the 28 convex uniform honeycombs.
The faces of this honeycomb's cells form four families of parallel planes, each with a 3.6.3.6 tiling.
Its vertex figure is an isosceles antiprism: two equilateral triangles joined by six isosceles triangles.

Famous quotes containing the words quarter and/or cubic:
“In the haunted house no quarter is given: in that respect
It’s very much business as usual. The reductive principle
Is no longer there, or isn’t enforced as much as before.”
—John Ashbery (b. 1927)
“One of the great natural phenomena is the way in which a tube of toothpaste suddenly empties itself when it hears that you are planning a trip, so that when you come to pack it is just a twisted shell of its former self, with not even a cubic millimeter left to be squeezed out.”
—Robert Benchley (1889–1945)
