We present a columnar cluster with 46 atoms per repeat distance which force
s a quasicrystal when space is filled by interpenetrating copies of itself.
The atomic positions in the resultant quasicrystal are remarkably similar
to those in models for real decagonal quasicrystals. The axes of the pentag
onal antiprism subclusters of this model reveal an even simpler tile decora
tion, with only three atoms, that forces a quasicrystal under certain const
raints. Published by Elsevier Science B.V.
