% File : SET686+3 : TPTP v8.2.0. Released v2.2.0.
% Domain : Set Theory (Relations)
% Problem : x in R^-1(D2) iff ?y in E : <x,y> in R (X to Y) & y in D2
% Version : [Wor89] axioms : Reduced > Incomplete.
% English : x is in the inverse of a relation R from X to Y applied to D2
% iff there exists an element y in E such that <x,y> is in a
% relation R from X to Y and y is in D2.
