This is joint work with Andrzej Skowro\’{n}ski. We investigate tame symmetric algebras constructed from surface triangulations, which generalize tame blocks of group algebras.

Tame blocks are the ones whose defect groups are dihedral, or quaternion,or semidihedral.

I will focus on the extended version (work in progress) which includes new algebras, and also includes some of the algebras from the block setting which we did not have in the first attempt.
