n! а. The formula, P(n,r),nPr = where 0<rs<n is for (n-r)!’ c. Permutations of n elements taken r at a time d. Permutation with Repeated Elements a. Circular Permutation b. Factorial Notation b. When things are arranged in places along a closed curve or circle, in which any place may be regarded as the first or last place, they form a circular permutation. Thus, with n distinguishable objects we have (n-1)! arrangements. a. Circular Permutation c. Factorial Notation b. Combination d.
