Description
Finite enumerated sets require that their list
methods and iter
methods return elements in the same order. This is tested in sage.categories.enumerated_sets.EnumeratedSets.ParentMethods._test_enumerated_set_iter_list
, but the test is not run if the number of elements is larger than a bound. #14284 changed that bound from 100 to 729, revealing the following bug:
sage: G = GL(2, 5) sage: TestSuite(G).run() # G.max_test_enumerated_set_loop = 500; TestSuite(G).run() # before :trac:`14284` Traceback (most recent call last): ... AssertionError: [2 0] [0 1] != [0 1] [1 0]

It is not clear because GL(2,5)
is no longer in the category of (finite) enumerated sets.
