Ticket #16820, comment 123
initial v1 63 63 + return A.subalgebra(gens) 64 64 }}} 65 I don't see why this should be a subalgebra ( unless subalgebra just meansvector subspace). Counterexamples can easily be obtained if self (e.g.) is a free Lie algbera and L is the span of a single generator. (And that's just for the case when self and L both are Lie subalgebras; but the method is probably useful in higher generality.)65 I don't see why this should be a subalgebra (it is just a vector subspace).

And why define `K` and `LK` if you could just iterate over `B` and `LB`?
