Abstract: We report on the numerical analysis of the area correlations in spin foamgravity on a single 4-simplex considered by Rovelli in PRL 97 2006 151301. Wecompare the asymptotics and confirm the inverse squared distance leadingbehaviour at large scales. This supports the recent advances on testing thesemiclassical limit of the theory. Furthermore, we show that the microscopicdiscreteness of the theory dynamically suppresses and regularizes thecorrelations at the Planck scale.
