I’ve been revisiting this stuff, although not quite in the same way. Inorganic Chemistry is fun, but not as fun as mineralogy was!

Hey Dr. Pollock! Does the four fold/two fold correspond to the subscript in the axes of rotation notation (A_4/A_2)? Or is the subscript supposed to be the total number of axes present in the crystal? And can there not be a horizontal plane of symmetry in the crystal? Or would that be the center of symmetry? See you in class tomorrow!
