Given four points in a plane, defined by their coordinates, there are 4!=24 permutations of those points.
The scripts computes the area of the 24 different quadrilaterals with the shoelace formula and plot them.
The maximal area found, seems to correspond to non self crossing direct quadrilaterals.

This script generates N random points in a plane, then it builds all the combinations of two (three or four) points in N points.
The function nclosestpoints, returns the n closest pair of points .
The function nsmallesttriangles returns the n smallest triangles according to their area.
The function trianglesbellow returns all triangles with an a…
