Abstract

Let M0,5R\overline{{\mathcal M}_{0,5}^{\mathbb R}} be the Deligne-Mumford compactification of the moduli space of genus 0 real algebraic curves with 5 marked points. By L(M0,5R){\mathcal L}(\overline{{\mathcal M}_{0,5}^{\mathbb R}}) we denote its orientation cover. The cell decomposition of L(M0,5R){\mathcal L}(\overline{{\mathcal M}_{0,5}^{\mathbb R}}) is a dessin d'enfant of the genus 4. In this paper we compute the Belyi pair for this dessin. In particular, it appears that the corresponding curve is a celebrated Bring curve.
