WebSo, this Merkle tree can sign up to 8 signatures using a signature size of 3 hashes (plus whatever hashes the lower level Winternitz uses). In general, a Merkle tree of height h can sign 2 h messages by revealing h internal nodes. Now, let us consider a Merkle tree where each internal node is 3 lower level nodes hashed together.
