for n being Element of NAT
for T being connected admissible TermOrder of n
for L being non degenerated non trivial right_complementable almost_left_invertible well-unital distributive Abelian add-associative right_zeroed associative commutative doubleLoopStr
for G being Subset of (Polynom-Ring (n,L)) st not 0_ (n,L) in G & ( for g1, g2 being Polynomial of n,L st g1 in G & g2 in G & not HT (g1,T), HT (g2,T) are_disjoint holds
PolyRedRel (G,T) reduces S-Poly (g1,g2,T), 0_ (n,L) ) holds
