limcimolemlt	|- ( ph -> ( abs ` ( X - Y ) ) < ( abs ` ( X - Y ) ) )

Distinct variable groups:   w, A   z, A   B, q   w, B   z, B   C, q   z, D   w, F   z, F   w, G   w, X   z, X   w, Y   z, Y

Allowed substitution hints:   ph( z, w, q)   A( q)   C( z, w)   D( w, q)   S( z, w, q)   F( q)   G( z, q)   K( z, w, q)   X( q)   Y( q)

Proof of Theorem limcimolemlt

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