#16131 ⟨a, b | aab=aa, bbaa=ba⟩

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 = a² and a ⋅ a = a², however ab ≠ a
Not right cancellative, because right multiplication by a is not injective:
- ba ⋅ a = ba and b ⋅ a = ba, however ba ≠ b

Format:	Pretty Plain
