Above is a 24-sided polygon.
What is the minimum rotation to map any vertex to it's next vertex?
We know that it takes 360 degrees to map it back to itself.
However, if vertices are indistinguishable, any rotation about the centre that maps a vertex to a neighbouring vertex will be the minimum angle required.
