I present new Stickers-MOD: Four-Color Cube

Many people know the famous mathematics the four color theorem. Any map in a plane or sphere can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color.
https://en.wikipedia.org/wiki/Four_color_theorem , http://mathworld.wolfram.com/Four-ColorTheorem.html

I found the pattern for coloring any cube in 4 colors to these rules. We received a very complex mathematical puzzle. if you want to solve it, you do not know the final pattern, but you know the rules of placement!

very similar puzzles: Sudoku, Qubami, Krenol, Respect cubes
