The polygons overlap with transparency, so 50 polygons could in theory create up to 2^50 unique regions. Think Venn diagram with every possible combination of overlapping areas, any combination of the 50 sets of points. (This is possible if the Venn areas are not convex.)
Realistically, it looks like the final result has somewhere upwards of 200 unique areas created by various overlaps of the 50 polygons.
