Problem statement
2.[Wor] Consider the tree of shifted standard Young tableaux, with the tree structure generated by containment. Computation suggests that the only automorphism of (as an unlabeled tree) is the identity. Computation further suggests that each node of is uniquely determined by the census (cardinalities) of the ranks of the subtree rooted at the node.
