  • Brief notes on the Normal class of isometric system

    These are hex octahedral, hex tetrahedral, diploidic, gyroidal and tetartoidal. The hex octahedral class is the normal class of isometric system as it shows maximum symmetry among all classes and also as galena type after the characteristic mineral galena that crystallizes in this class.
