# 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)`
