#16132 ⟨a, b | aab=aa, bbaa=bb⟩

Properties

Sum of relation sides is 11
Infinite non-cancellative non-commutative monoid
Element ba has infinite order
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ ab = a² and a ⋅ a = a², however ab ≠ a
Not right cancellative, because right multiplication by b is not injective:
- b² ⋅ b = b² and b ⋅ b = b², however b² ≠ b
