| For about 99.5% of all triangulations the canonical hash value (computed by [[http://pallini.di.uniroma1.it/|nauty]]) identifies the triangulations uniquely. In the remaining cases the function ''retrieve_by_canonical_hash'' returns the first triangulation and issues a warning. | For about 99.5% of all triangulations the canonical hash value (computed by [[http://pallini.di.uniroma1.it/|nauty]]) identifies the triangulations uniquely.
