#7162 ⟨a, b, c | aa=1, abbb=cb⟩

Properties

Sum of relation sides is 8
Infinite non-cancellative non-commutative monoid
Element ab has infinite order
Not right cancellative, because right multiplication by b is not injective:
- c ⋅ b = ab³ and ab² ⋅ b = ab³, however c ≠ ab²

Format:	Pretty Plain
Word:
	Enter a word above to compute its normal form. Tips: Lowercase letters stand for generators. Spaces are ignored. Numbers repeat the previous letter, e.g. `b90`.
Strategy:	Leftmost Rightmost
Result:	1 1

Reduction order:
- Left-to-right recursive path with deg(a) = deg(b) = 0, a < b; deg(c) = 1
Certificate: derivations of all rewriting rules from the defining relations.

#	Rule	Proof
1.	a² ⇒ 1	[1]
2.	cb ⇒ ab³	[2]

# abc:aa=1,abbb=cb ab/c - -
aa=1
cb=abbb

The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
