----------------------------+-----------------------------------------------
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]
}}}
