#20243 ⟨a, b | aba=a, bbbb=aab⟩

Properties

Sum of relation sides is 11
Infinite non-cancellative non-commutative monoid
Element bab has infinite order
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ ba = a and a ⋅ 1 = a, however ba ≠ 1
Not right cancellative, because right multiplication by a is not injective:
- ab ⋅ a = a and 1 ⋅ a = a, however ab ≠ 1

Format:	Pretty Plain
