Although n-fold rotations for n differing from 2, 3, 4, and 6 are forbidden in the strict sense of perfect crystallographic symmetry (these constitute the so-called crystallographic restriction ), there are exotic materials called quasicrystals that display these symmetries. — “Quasicrystal -- from Eric Weisstein's World of Physics”,

- Advanced Stealth Top Secret Nuclear Powered Flying Triangle TR-3B Contains Real Video Footage Of TR-3B In Action! An advanced mercury, thallium, barium & iron ferrofluid is used. The ferrofliud is propelled in a circular ring with pulsing magnetic coils and is rotated at 60000 rpm under 250 atmospheres of pressure creating a vortex and magnetic field around the craft. The circular ring is made from aluminium with an internal quasicrystal layer and this is super-cooled at -125 degrees celsius. Hydrogen - oxygen variable vectored rocket engines are used for propulsion within a planetary atmosphere and helicon double layer thrusters -- plasma/ion thrusters are used for space travel. This craft can refuel the hydrogen -- oxygen tanks on any planet which has liquid or frozen water as it can convert H2O into hydrogen and oxygen using electrolysis. The rocket engines and a mini nuclear reactor are used to generate electrical power for this craft. The control area is within a radiation capsule to protect the occupants from radiation sickness. The capsule is in the center of the super-cooled circular ring, which helps to keep them cool too. This craft travels further, faster, stealthier than any other type and can used for space travel!

- Quasicrystal Cluster Complex Tutorial (Zen Magnets) This tutorial exhibits the assembly procedure for the Quasicrystal Cluster Complex. Please watch my solid regular icosahedron tutorial in order to construct the icosahedral core, you will require it to finish. You will also need an entire mandala set, or eight sets of whatever brand of spheres you're using. The twelve subsections are in fact Rhombic Icosahedra, and using the technique shown, you can inflate the size of each sub-section to the next scale, yielding a larger model. The Uber cluster complex is that example. Have fun making this shape, it is very durable and fun to play with, in that the panels are removable and click back into place effortlessly. Additionally, 20 hexagons, each made from 19 spheres, can be added to the 3-fold symmetry points surrounding the quasicrystal, giving it a very spherical appearance. My Hyper Cluster Matrix is assembled out of twelve of these.
