This is a bit disconcerting:
sage: Set(['a', 'b', 'c'])
{'a', 'c', 'b'}
sage: Set(['a', 'b', 'c', 'd'])
{'a', 'c', 'b', 'd'}
sage: Set(['a', 'b', 'c', 'd', 'e'])
{'a', 'c', 'b', 'e', 'd'}
Bug? It doesn't seem to happen with lists of numbers.
Best,
Alex

In fact, the reason this is bothering me right now is that I'm writing
code for working with free groups on sets, and I end up with something
like
sage: G.a, b, c = FreeGroup()
sage: G
Free Group on the Set {a, c, b}
sage: b
