#1041 ⟨a, b, c | ab=c, bca=c⟩
Contents
- Properties
- Rewriting system
- Other submonoids of same group
- Isomorphic instances
- Sum of relation sides is 7
- Infinite cancellative non-commutative monoid
- Element a has infinite order
- Submonoid of enveloping group: ⟨a, b | aaba-1b-1⟩
-
Embedding: φ(a) = ab, φ(b) = b-1, φ(c) = a
- Reduction order:
- Left-to-right recursive path with deg(a) = deg(c) = 0, a < c; deg(b) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
