[GAP Forum] question

[taleea jalaeeyan]

Thank you gap for answering me.
1- how can i define commutators of wight more than 3 to gap?
2- is the concept of Quadratic Non Residue (mod p) is defined for gap?
how can i define it for a presentation of a group?
how can i define the following presentation in gap
 \langle x‎, ‎y |x^{p^{2}}=y^{p}=1‎, ‎[x‎, ‎y‎, ‎x]=1‎, ‎[x‎, ‎y‎,
‎y]=x^{np}‎, ‎[x‎, ‎y‎, ‎y‎, ‎y]=1   \rangle
when n is quadratic non residue (mod p)?
