Therefore the maximum number of points at which the diagonals of a n-gon will intersect is the combination of n points taken four at a time. Your R (n) formula seems to be correct.

Number of Diagonals – Mathigon
WebP= the number of unordered pairs (a,b), where a,b are 2 parallel diagonals in a regular n-gon. It is not hard to find a precise formula for P: for every direction w, we have to count how many diagonals are on this direction. If there are z=z(w) diagonals, z 2 is the contribution of w. Any direction is given by the diagonals which WebTo find the number of diagonals in a polygon, we multiply the number of diagonals per vertex ( n − 3) (n-3) (n− 3) by the number of vertices, n n n , and divide by 2 (otherwise each … WebIn particular, it is impossible to have 8 or more diagonals of a regular n-gon meeting at a point other than the center.
