Automorphisms of powers of linearly ordered sets
Let S be a bounded, partially ordered set, and n a positive integer. We investigate automorphism groups of S-n and of S-[n], the non-decreasing n-tuples of S-n. Our main interest is in the case where S is the unit interval of real numbers with the usual order.
