Two cube styles with some different properties are selectable:
Standard cubes with unmarked centres available for full cube size range 2 to a maximum size that has a size 99 program limit but that limit may not be reachable if a monitor with insufficient vertical and horizontal pixels (often referred to as resolution) is not in use.
Cubes with marked centres available in the size 3 to about 32 range for many screens when numerical marking is in use and up to program limit when corner marking extension applies (but can be more or less depending on screen resolution).
