Various vector-like utilities for permutation objects such as
length, names(), etc
# S3 method for word
length(x)
# S3 method for permutation
length(x) <- value
# S3 method for word
names(x)
# S3 method for word
names(x) <- value
permutation object
In function names<-.word(), the new names

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
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.
