After Mathematica 1.2, our marketing materials had a whole collection of hyperbolic Platonic solids, but by the time Version 2.0 arrived in 1991 we’d decided our favorite was the hyperbolic dodecahedron:

What are Spikeys and How Do They Work? | Just Online

There are other ways to build rhombic hexecontahedra out of other polyhedra. Five intersecting cubes can do it, as can 182 dodecahedra with touching faces: In another top table clash in the C League Innes Spikeys took an 8-4 victory against Clachnaharry and both these sides are now on eight points and lead the table.The effects of drink spiking vary depending on what you’ve been spiked with. Your symptoms could include:

Anti-Spiking Products Arrive at the SU

They started the mens match in style winning all six of the opening group and followed that up with another seven sets to win 13-3. Fife’s Colin Hepplewhite was their best on the day with a 78.82 average whilst Iain Campbell for Moray hit a 78.08. None of this was settled when in the early 1980s electron diffraction crystallography on a rapidly cooled aluminum-manganese material effectively showed five-fold symmetry. There were already theories about how this could be achieved, and within a few years there were also electron microscope pictures of grains that were shaped like rhombic triacontahedra: Raging Storm Raigmore’s 8-4 win against Culloden Moor Inn enabled them to move into third spot in the table, a point ahead of Culloden but having played one more game. The Union works closely with the University and the Police to prevent and reduce the impact of drugs on campus and part of this partnership involves the sharing of CCTV footage of incidents and pushing for prosecution where possible. Seaforth Club made up some ground on the leaders with an 8-4 win over Still Game in Nairn and they inch up the table into fourth spot.

A couple of minutes later, I had homed in on the rhombic hexecontahedron, and at exactly 12:24:24am on February 7, 2009, I rotated it into essentially the symmetrical orientation we now use: In 2009, we were getting ready to launch Wolfram|Alpha—and it needed a logo. There were all sorts of concepts: A few years later, we tweaked the facet shading slightly, giving what is still today the logo of Wolfram|Alpha: May 19, 2009. http://blog.wolframalpha.com/2009/05/19/whats-in-the-logo-that-which-we-call-a-rhombic-hexecontahedron.

Spiked? - Royal Holloway, University of London

And, yes, the shapes here are rhombuses, though not golden rhombuses. But with angles 36°,144° and 72°,108°, they arrange with 5- and 10-fold symmetry. Drinkstuff says: It is difficult to introduce a substance into a straw surreptitiously and also the straws are normally bent when in use. It had been thought about in the design stage that if a criminal did manage to get a substance into a straw it would make the straw taste bad immediately. Also we know from statistics that the majority of drink spiking is done by adding alcohol to a soft drink, or more alcohol to an Alco pop type drink. By using Spikey, this criminal activity is made virtually impossible. Across the 120 edges of the rhombic hexecontahedron, the 60 “inward-facing hinges” have dihedral angle 4𝜋/5=144°, and the 60 “outward-facing” ones have dihedral angle 2𝜋/5=72°. The solid angles subtended by the inner and outer vertices are 𝜋/5 and 3𝜋/5. Making up the leading three teams are Tarradale who have led from the first match and stay at the top despite being idle this week. In the City Taxis Inverness Summer Darts League the main title challengers are starting to emerge at the half-way stage.The top two sides in the B League have identical records with three wins and a defeat each, both sitting on 6 points after this weeks matches. Legion CSE took out the Raigmore 9-3 and Innes Bar defeated Innes X 8-4 in the derby match.
