Permutations

Description

A permutation is a ordered arrangement of the set of objects given.The number of permutations can be calculated by

(1)
\begin{equation} n!. \end{equation}

The Sage cell below gives back the set of all possible permutations of the numbers $1,2,3,4,5$.

Sage Cell

Code

S=Permutations([1,2,3,4,5])
print "We expect ", len(S.list() ), "items below"
S.list()

Options

Option

We can do the same process thing for non-numerical objects as well. In the Sage cell below, we see all the possible permutations of Kings, Queens, and Jacks.

Code

S=Permutations([1,2,3,4,5])
print "We expect ", len(S.list() ), "items below"
S.list()
