# Appendix on Generating the Hecke Algebra

**Abstract**

In this appendix to Lario and Schoof's Some
computations with Hecke rings and deformation rings (to appear in
Experimental Mathematics),
we apply a result of J. Sturm to obtain a
bound on the number of Hecke operators needed to generate the Hecke
algebra as an abelian group. This bound was suggested to the authors
of this appendix by Loic Merel and Ken Ribet.
