Permutation and Combination

Given a set of n elements, a permutation (also
called an "arrangement number" or "order") is
the number of ways of obtaining an ordered
subset of r elements from the original set of n
elements. Obviously,
being natural numbers. Permutation is defined
by the following formula:
1: Convert
° to rectangular coordinates (x,y).
