427427As before, the root of the binary tree (i.e., the whole noun) is at address `1`. For the node of a tree at any address `b`, where `b` is a binary number, you get the address of its head by concatenating a `0` to the end of `b`; and to get its tail, concatenate a `1` to the end. For example, the head of the node at binary address `111` is at `1110`, and the tail is at `1111`.
