We describe an algorithm that we used to compute theq-expansions of all weight 2 cusp forms of prime level at mostand dimension at most 6. We also present an algorithm that we used to verify that there was only one cusp form of dimension 7 or more per Atkin-Lehner eigenspace for prime levels betweenand. Our algorithm is based on Mestre’s Méthode des Graphes, and involves supersingular isogeny graphs and Wiedemann’s algorithm for finding the minimal polynomial of sparse matrices over finite fields.
