##### Various vector-like utilities for permutation objects.

Various vector-like utilities for permutation objects such as
`length`

, `names()`

, etc

##### Usage

```
# 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
```

##### Arguments

- x
permutation object

- value
In function

`names<-.word()`

, the new names

##### 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.

##### Examples

```
# NOT RUN {
x <- rperm(9,5)
names(x) <- letters[1:9]
data(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
# }
```
