#12637 ⟨a, b | babb=ba, bbbb=b⟩

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 c is not injective:
- c ⋅ b = c and c ⋅ 1 = c, however b ≠ 1
Not right cancellative, because right multiplication by c is not injective:
- b³ ⋅ c = c and 1 ⋅ c = c, however b³ ≠ 1

Format:	Pretty Plain
