Abstract
Employing Monte-Carlo simulation we study the phase diagram of a Z2 ga uge field coupled to simplicial quantum gravity. We localize a critica l point of the model where both the matter and gravity sectors have a second order phase transition. We found the value of the critical inde x gamma(g) = 0.16(4) of the gravity susceptibility at the critical poi nt.
