Polymorphic lambda calculus: the Church-Rosser property

WebA Thue system T is Church-Rosser if, for every choice of x and y, x <-sy implies that for some z, xSz and ySz. Intuitively, in a Church-Rosser Thue system T, if two strings are reduced (using the replacement rules of S) to two distinct irreducible strings, then the two strings are not congruent.

Finally, we'll prove that ⇒* (a sequence of zero or more walks) has the diamond property, and we'll use that to "fill in the diamond" and thus to prove the Church-Rosser Theorem. Task 1.
