Rotoinversion
"A chiral point group is one without any rotoinversion symmetry elements. Rotoinversion (also called an 'inversion axis') is rotation followed by inversion; for example, a mirror reflection corresponds to a twofold rotoinversion" I may not be so familiar, but this sounds counter intuitive. Something that is chiral should have no rotational symmetry. However it should have mirror symmetry. In this case I do believe it has rotoinversion symmtery, and thus I would agree with the second sentence that it has "twofold rotoinversion." As these two sentences currently stand, I don't believe they agree with each other. I think "rotoinversion symmetry elements" should be instead "rotational symmetry elements." Can someone confirm this? Srodrig (talk) 15:53, 15 June 2015 (UTC)

More laymen-friendly?
Could someone qualified please expand this article to render it more approachable those not already familiar with the subject material? At the moment, it reads a bit like someone's textbook notes: more of a reference to remind one of what they already learned. Thanks!Ernest Ruger (talk) 17:39, 17 August 2014 (UTC)
 * More approachable is this article Point reflection. In my humble opinion, the Centrosymmetry article should be merged into Point reflection. Bor75 (talk) 06:46, 18 August 2014 (UTC)
