Definitions

To make understandable explanations for solving the Cube, it's necessary to give each part of the Cube definite names. On my site, the parts of the Cube are named as follows:

The Rubik's Professor Cube consists of the following components:

- 8 corners:

- 36 edge pieces,	which can be subdivided into (based on their position):
	24 outer and	12 middle edge pieces

- 54 side pieces,	which can be subdivided into (based on their position):
	6 center side pieces	24 edge side pieces and	24 corner side pieces

Each 25 (outer layers) or 16 pieces (inner layers), which are on the same plane, form a unity (in the following called "layer") and can be moved together. By 90° or 180° turns of these layers, you can mix up the Cube or solve it.
The Professor Cube consists of the following 15 layers:

- 6 outer layers:

- 9 middle layers:

The middle layers can, based on their positions, be subdivided into:
- 3 central middle layers:

- 6 outer middle layers:
