Specifically, a triangulation that includes an inner edge is treated. The computation leverages the recently introduced effective spin foam models, which are particularly numerically efficient. Previous work has raised the concern of a flatness problem in spin foam dynamics, identifying the potential for the dynamics to lead to flat geometries in the small $\\hbar$ semiclassical limit. The numerical results presented here expose a rich semiclassical regime, but one tha","authors_text":"Bianca Dittrich, Hal M. Haggard, Seth K.
