Actually subs(a="1+x")
would not be sensible (the free group is not an algebra) but something like
subs(a="abA")
might be useful and/or interesting.
Also observe that the internal representation for a freegroup
object is a list of integer matrices, symbols like a
and b
are created by the print method.
In the
freealg
package,subs()
has a nice feature:But this does not work in the
freegroup
package:and it would be nice if it did.
