Ahierarchyon a setS, also called atotal partition of S, is a collectionof subsets ofSsuch that, each singleton subset ofSbelongs to, and ifthenequals eitherAorBor. Every exchangeable random hierarchy of positive integers has the same distribution as a random hierarchyassociated as follows with a random real treeequipped with root element 0 and a random probability distributionpon the Borel subsets of: given, letbe independent and identically distributed according top, and letcomprise all singleton subsets of, and every subset of the formasxranges over, whereF(x) is the fringe subtree ofrooted atx. There is also the alternative characterization: every exchangeable random hierarchy of positive integers has the same distribution as a random hierarchyderived as follows from a random hierarchyon [0, 1] and a familyof i.i.d. Uniform [0,1] random variables independent of: letcomprise all sets of the formasBranges over the members of.
