Right-angled Artin groups generalize abelian and free groups. The only relations in RAA Gs is that some generators commute. We get right-angled Coxeter group as a quotient of a RAAG by killing a square of each generator. The Cayley complex associated to RAAG or RACG is a square complex and we can exploit its geometry to get an algebraic statement about these groups. Namely, we get that RAAG or RACG either is a direct product, or it surjects on alternating groups in many ways.
