| Dec 7, 2014 at 5:59 | comment | added | Alex Suciu | Have you tried looking at the book on Combinatorial group theory by Magnus, Karrass, and Solitar? | |
| Dec 7, 2014 at 5:54 | comment | added | Zuriel | I suppose that this result about $\Gamma_kP_n$ is known; where can I find a reference? | |
| Dec 7, 2014 at 5:48 | comment | added | Alex Suciu | By induction on $n$, using the known structure of $\Gamma_k F_r$. | |
| Dec 7, 2014 at 5:45 | comment | added | Zuriel | Thanks for the answer! So you mean that there is a split exact sequence $1\to \Gamma_kF_{n-1}\to\Gamma_kP_n\to\Gamma_kP_{n-1}\to1$, right? Hence how to find $\Gamma_kP_n$ exactly? | |
