A *rhonic* polycube is a polycube whose cells form
the shape of a rhombic dodecahedron.

The smallest rhonic polycube whose volume is a multiple of 5 is the 5th rhonic polycube, shown above on the right. It has 185 cells, so it can be tiled with 37 pentacubes.

Here I show which pairs of pentacubes can tile this polycube,
using at least one of each pentacube.
A prime mark (**′**) after a letter denotes a mirror image.
For example, **S′** is the mirror image of
**S**.
To see a tiling, click on the corresponding entry in the table below.
Missing entries indicate unsolved cases.

The **B** and **Q** pentacubes can each
tile this polycube alone.
To see such tilings, click on the corresponding index link in the table.

If you solve an unsolved case, please write.
