[GAP Forum] The command "IsIdentical" can not work.

[Mathieu Dutour]

Well, the function "IsIdentical" simply does not exist.
GAP is a functional language. The function themselves
are variables.

But if you want you have:
gap> IsIdenticalObj(1,1);
true

or
gap> 1=1;
true

I am not sure of the difference between both.
