Abstract

In this note, we comment on Calabi-Yau spaces with Hodge numbers h1,1=3h_{1,1}=3 and h2,1=243h_{2,1}=243. We focus on the Calabi-Yau space WP1,1,2,8,12(24)WP_{1,1,2,8,12}(24) and show how some of its instanton numbers are related to coefficients of certain modular forms. We also comment on the relation of four dimensional exchange symmetries in certain N=2N=2 dual models to six dimensional heterotic/heterotic string duality.
