Read the background
Every proper unit-distance colouring of the plane whose unit ball is the regular 14-gon uses at least five colours.
Why it matters
If correct, resolves the 14-gon case of a stated polygon-colouring question; the exact chromatic number remains five or six.
What counts as progress
Can the regular 14-gon Minkowski plane be properly coloured with four colours?
