theorem Th26: :: JORDAN3:26

for f being FinSequence of (TOP-REAL 2)
for p being Point of (TOP-REAL 2) st p in L~ f holds
( ( p = f . ((Index (p,f)) + 1) implies len (L_Cut (f,p)) = (len f) - (Index (p,f)) ) & ( p <> f . ((Index (p,f)) + 1) implies len (L_Cut (f,p)) = ((len f) - (Index (p,f))) + 1 ) )
