If you know the *position* p of a node, then p.parent() is its parent *position* and you are done. But if you just know the (v)node, then there is no such thing as *the* parent of the node. Instead, v.parents is a list of the vnodes having v as a child. Note that the same vnode may appear multiple times in any v.parents list. Depending on what you want to do, you may want to traverse the entire tree, looking for positions p such that p.v == v for the given vnode. You can then decide what to do with the found positions. HTH. Edward P.S. Yes, the distinction between positions and nodes can be confusing, but the payoffs are enormous. For example, Leo can clone any node/tree in O(0) time.
