Description: Different components can be set in any order. (Contributed by Jim Kingdon, 20-Feb-2025.)

Hypotheses

Ref	Expression
setscomd.a	|- ( ph -> A e. Y )
setscomd.b	|- ( ph -> B e. Z )
setscomd.s	|- ( ph -> S e. V )
setscomd.ab	|- ( ph -> A =/= B )
setscomd.c	|- ( ph -> C e. W )
setscomd.d	|- ( ph -> D e. X )

Assertion

Ref	Expression
setscomd	|- ( ph -> ( ( S sSet <. A , C >. ) sSet <. B , D >. ) = ( ( S sSet <. B , D >. ) sSet <. A , C >. ) )

Proof of Theorem setscomd

Dummy variables a b are mutually distinct and distinct from all other variables.
