#485 ⟨a, b | aabb=1, abba=1⟩
Quick links
- Properties
- Rewriting system
- Isomorphic instances
- Presentation has sum-of-sides 8
- Infinite non-Abelian group
- Inverses of generators:
- a-1 = ca
- b-1 = a2b
- c-1 = a2
- Auxiliary generators:
- c = bb
- Reduction order:
- Left-to-right shortlex with c < a < b
- Certificate: derivations of all rewriting rules from the defining relations.
- Morphocompletion: how the auxiliary generators were found.
