#16429 ⟨a, b | aba=ab, bbba=aa⟩

Properties

Sum of relation sides is 11
Infinite non-cancellative non-commutative monoid
Element b has infinite order
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ ab = ab and a ⋅ b = ab, however ab ≠ b
Not right cancellative, because right multiplication by b is not injective:
- a² ⋅ b = ab and a ⋅ b = ab, however a² ≠ a
