#13213 ⟨a, b | abb=aba, bab=bb⟩

Properties

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