let p be Point of (TOP-REAL 2); :: thesis: ( f is almost-one-to-one & f is special & f is unfolded & f is s.n.c. & p in L~ f & p <> f . 1 implies R_Cut f,p is being_S-Seq )
assume ( f is almost-one-to-one & f is special & f is unfolded & f is s.n.c. & p in L~ f & p <> f . 1 ) ; :: thesis: R_Cut f,p is being_S-Seq
then R_Cut f,p is_S-Seq_joining f /. 1,p by Th39;
hence R_Cut f,p is being_S-Seq by JORDAN3:def 3; :: thesis: verum
