#3429 ⟨a, b | aaabaaaaba=a⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 11
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ a2ba4ba = a and a ⋅ 1 = a, however a2ba4ba ≠ 1
- Not right cancellative, because right multiplication by a is not injective:
-
a3ba4b ⋅ a = a and 1 ⋅ a = a, however a3ba4b ≠ 1
- Reduction order:
- Left-to-right shortlex with a < b
- Certificate: derivations of all rewriting rules from the defining relations.
# ab:aaabaaaaba=a ab - -
