Summary

Represents a cell in a PentaCell.Grid consisting mostly of pentagons and a few thin rhombuses that fill the gaps.

Remarks

Represents a cell in a two-dimensional grid that is either a pentagon or a thin rhombus (PentaCell.IsRhombus). The cells are represented by a PentaCell.Level (innermost pentagon is Level 0, each subsequent layer grows outwards in all directions), an PentaCell.Element number and a PentaCell.Rotation. Since the structure has pentagonal symmetry, the PentaCell.Element property only counts one fifth of the elements in a layer, while the values 0–4 of PentaCell.Rotation are then used to create the 5 symmetric copies of those elements.
