Abstract.

We construct a crystallization of the real projective space \({\mathbb{R}}P^n\) whose associated contracted complex is minimal with respect to the number of n-simplexes. Then we compute the regular genus of \({\mathbb{R}}P^n\), which is the minimum genus of a closed connected surface into which a crystallization of \({\mathbb{R}}P^n\) regularly embeds.
