Query: Hochschild cohomology ring for self-injective algebras of tree class
  $E_6$. II   We describe the Hochschild cohomology ring for a family of self-injective
algebras of tree class $E_6$ in terms of generators and relations. Together
with the results of the previous paper, this gives a complete description of
the Hochschild cohomology ring for a self-injective algebras of tree class
$E_6$.
