#3545 ⟨a, b, c | ab=aa, bc=aa⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 8
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ b = a2 and a ⋅ a = a2, however b ≠ a
- Reduction order:
- Left-to-right shortlex with a < b < c
- Certificate: derivations of all rewriting rules from the defining relations.
# abc:ab=aa,bc=aa abc - -
ab=aa
bc=aa
aac=aaa
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
