The EOS symbol is a chestahedron. What is a chestahedron? What does that even mean? These are some of the questions that came up for me. So i decided to investigate further.
Chetahedron is a 7 sided shape that was discovered by Frank Chester...not so long ago...
Here is an interesting video of Frank Chester, sharing his process of discovery.
