[**Abstract**]{}

We present a detailed analysis of a recently introduced version of Causal Dynamical Triangulations (CDT) that does not rely on a distinguished time slicing. Focussing on the case of 2+1 spacetime dimensions, we analyze its geometric and causal properties, present details of the numerical set-up and explain how to extract “volume profiles". Extensive Monte Carlo measurements of the system show the emergence of a de Sitter universe on large scales from the underlying quantum ensemble, similar to what was observed previously in standard CDT quantum gravity. This provides evidence that the distinguished time slicing of the latter is not an essential part of its kinematical set-up.

Introduction
============

First attempts in the 1990s to define quantum gravity nonperturbatively with the help of Dynamical Triangulations (DT) were based on an intrinsically Euclidean path integral, whose configuration space consists of four-dimensional, curved Riemannian spaces. DT works with a regularized version of this space in terms of triangulations, piecewise flat spaces of positive definite metric signature. Its elementary building block is a four-simplex, a generalization to four
