#16264 ⟨a, b | aab=ba, bbab=bb⟩
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 b is not injective:
-
b ⋅ b2 = b2 and b ⋅ b = b2, however b2 ≠ b
- Not right cancellative, because right multiplication by b is not injective:
-
b2 ⋅ b = b2 and b ⋅ b = b2, however b2 ≠ b
- Reduction order:
- Right-to-left recursive path with deg(a) = 0; deg(b) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
# ab:aab=ba,bbab=bb reversed:a/b - -
ba=aab
aaaabb=bb
bbb=bb
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
