The automorphism group of $M_{0,n}^{\text{trop}}$ and ${\overline{M}}_{0,n}^{\text{trop}}$

Abstract

In this paper we show that the automorphism groups of $M_{0,n}^{\text{trop}}$ and ${\overline{M}}_{0,n}^{\text{trop}}$ are isomorphic to the permutation group $S_n$ for $n\ge 5$, while the automorphism groups of $M_{0,4}^{\text{trop}}$ and ${\overline{M}}_{0,4}^{\text{trop}}$ are isomorphic to the permutation group $S_3$.
