Eta-quotients and Embeddings of $X_0(N)$ in the Projective Plane

Abstract

In this paper we find projective plane models of $X_0(N)$ by constructing maps from $X_0(N)$ to the projective plane using modular forms. We use eta-quotients of weight 12. We find those eta-quotients of weight 12 which have maximal order of zero at the cusp $\infty$.
