identity different in permutations package and the freegroup package #13

Closed RobinHankin closed 1 month ago

RobinHankin commented 6 years ago

In the freegroup package, the identity is given by id() and in the permutations package the identity is given by variable id

I am not sure whether consistency is particularly desirable and, if so, which approach is better.

This issue is only material when both permutations and freegroup are loaded simultaneously. I am not sure why anyone would want this, but on the other hand I do not want to forbid it.

But for the sake of argument suppose we have a session with both packages loaded. What should "the identity" be in this case? The concept is common to both, but it would be oh-so-easy to type "id()" [or indeed "id"] at the command line and expect to get as.free(0) but actually get as.cycle(). I am not sure what is desirable in this situation.
