[GAP Forum] Question

[fahime babaee]

Dear Forum

Let $H$ and $K$  be finitely generated subgroups of the free group $F(n)$
such that $H\subseteq K$. We Know that $K$ is a free group. Now we choose
basis for $K$ and $H$ and I want to rewrite the basis of $H$ in the chosen
basis of $K$. I can do this calculation with hand by using automaton of $K$
but it take a long time. How can I do this with GAP?
