********************************
*********** Automata ***********
To give an automaton to GAP use the function Automaton
gap> Automaton("det",3,2,[ [ 0, 3, 0 ], [ 2, 3, 0 ] ],[ 3 ],[ 1, 3 ]);;
A random function is also available
gap> x := RandomAutomaton("det",3,2);;Display(x);
| 1 2 3
--------------
a | 3
b | 2 3
Initial state: [ 3 ]
Accepting states: [ 1, 3 ]
Now using Print and String you obtain
gap> Print(String(x));
Automaton("det",3,"ab",[ [ 0, 3, 0 ], [ 2, 3, 0 ] ],[ 3 ],[ 1, 3 ]);;
and through the use of copy/paste and some small changes it is easy to give your favourite automaton to GAP.

*********** Rational Expressions ***********
To give a rational expression to GAP use the function RationalExpression
gap> RationalExpression("aUba*","ab");
aUba*
