#1577 ⟨a, b | aaa=aa, aab=b⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 9
- Infinite non-cancellative non-commutative monoid
- Element b has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ a2 = a2 and a ⋅ a = a2, however a2 ≠ a
- Not right cancellative, because right multiplication by b is not injective:
-
a ⋅ b = b and 1 ⋅ b = b, however a ≠ 1
- Reduction order:
- Left-to-right shortlex with a < b
- Certificate: derivations of all rewriting rules from the defining relations.
# ab:aaa=aa,aab=b ab - -
ab=b
aaa=aa
