.. _spkg_database_mutation_class: database_mutation_class: Database of exceptional mutation classes of quivers ============================================================================ Description ----------- Contains a database of all exceptional mutation classes of quivers. Every file in the database is of the form ``mutation_classes_n.dig6`` for some ``n`` and - contains a ``cPickle.dump`` of a dictionary where - the keys are tuples representing irreducible exceptional quiver mutation types of rank ``n``, and - the values are all quivers in the given mutation class stored in canonical form as ``(dig6,edges)`` where - ``dig6`` is the dig6 data of the given ``DiGraph``, and - ``edges`` are the non-simply-laced edges thereof. - is obtained by running the function ``sage.combinat.cluster_algebra_quiver.quiver_mutation_type._save_data_dig6(n, types='Exceptional', verbose=False)`` SPKG Maintainers ---------------- - C.
