02-03- Fluorite #6.
78 atoms, 112 bonds, 14 polyhedra.
This time, I introduced an element of mathematics called the 4Color theorem: the regions of any map can be colored with only four colors, in such a way that any two adjacent regions have different colors. How many regions can we extend this to? It took over a hundred years to (mathematically) solve it!
My question was: a 4-color scheme does not exist in nature – how will it affect a semi-opaque to transparent fluorite crystal structure?
