Usage

length(x)
# S3 method for permutation
length(x) <- value

value

Details

These functions have methods only for word objects; cycle objects use the methods for lists. It is easy to confuse the length of a permutation with its size.

It is not possible to set the length of a permutation; this is more trouble than it is worth.

size

Examples

Run this code

x <- rperm(5,9)
x
names(x) <- letters[1:5]
x

megaminx
length(megaminx)   # the megaminx group has 12 generators, one per face.
size(megaminx)     # the megaminx group is a subgroup of S_129.

names(megaminx) <- NULL   # prints more nicely.
megaminx
