Sketch of the IMBH–BH–BH triple configuration. We mark the main quantities that characterise the triple: IMBH mass (M_IMBH), stellar BH masses (M_BH1, 2), and orbital semimajor axis and eccentricity of the IMBH–BH1 (a₁, e₁) and IMBH–BH2 (a₂, e₂) systems, and those that characterise the host cluster: gravitational potential (Φ_GC), total mass (M_GC), typical radius (r_GC), and velocity dispersion (σ_GC).
