#978 ⟨a, b, c | ab=a, bcc=a⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 7
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ b = a and a ⋅ 1 = a, however b ≠ 1
- Reduction order:
- Left-to-right shortlex with a < b < c
- Certificate: derivations of all rewriting rules from the defining relations.
# abc:ab=a,bcc=a abc - -
ab=a
acc=aa
bcc=a
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
