In the definition for Crystal Systems, the difference between Triclinic and Monoclinic, or Monoclinic and Orthorhombic, is due to: Restraining the axial cell lengths to be equal to each other. Restraining the cell angles to be equal to 90 degrees. The impossibility of placing regular pentagons into a repeating 3-dimensional lattice. The addition of independent symmetry elements. The recognition that a cell need not be primitive, but can be A, B, C, I or F centered.
