You're right. This is what I meant:
sage: L = [vector([1,0,0]), vector([1,2,0]), vector([1,0,3]), vector([1,0,0])]
sage: LL = [tuple(v.list()) for v in L]
sage: Set(LL)
{(1, 0, 0), (1, 0, 3), (1, 2, 0)}
But that is probably what you said in the first place.
Here's another idea:
sage: L = [vector([1,0,0]), vector([1,2,3]), vector([1,2,3]), vector([1,0,0])]
sage: iL = Set([L.index(v) for v in L])
sage: [L[i] for i in iL]
[(1, 0, 0), (1, 2, 3)]
Does this help in your situatiuon?
