% Domain : Set Theory (Relations)
% Problem : <x,z> in P(DtoE) o R(EtoF) iff ?y in E:<x,y> in P & <y,z> in R
% Version : [Wor90] axioms : Reduced > Incomplete.
% English : Let P be a relation from D to E, R a relation from E to F, x an
% element of D, and z in F. Then <x,z> is in P composed with R if
% and only if there exists an element y in E such that <x,y> is in
% P and <y,z> is in R.
