> But the UCLA investigators developed a technique that prevents that corrosion and showed that, in its absence, lithium atoms assemble into a surprising shape—the rhombic dodecahedron, a 12-sided figure similar to the dice used in role-playing games like Dungeons and Dragons.
I've never seen a rhombic dodecahedron d12 before. They do exist after a quick search, but the much more common d12 is just a dodecahedron, with pentagonal faces.

- jareklupinski 3y agothese look like someones trying to play a perspective trick on me how are they not the common/normal d12s
- sethhochberg 3y agoCount the edges of each flat face - five on a normal d12, four on this one
- jareklupinski 3y agoah i meant "how are they not" incredulously, as in these should be the ones endorsed by the creators i've always had a hard time differentiating between a d12 and its neighbors at a glance, but this would make it clearly stand out from the other shapes
