%0 Journal Article %T Comment on 3D Penrose Tiling of the Icosahedral Quasicrystalline Phase %A Lydon Swartzendruber %A Lawrence H. Bennett %J Physics %D 2015 %I arXiv %X A recent arXiv contribution makes the case that the quasicrystallinephase is due to twinning, albeit with a different twinning scheme than thatpresented by Pauling. It appears to us that this approach, though novel, hasno validity. %U http://arxiv.org/abs/1510.04572v1
