#917 ⟨a, b, c | aa=b, acc=a⟩

Properties

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 ⋅ c² = a and a ⋅ 1 = a, however c² ≠ 1

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(c) = 0, a < c; deg(b) = 1
Certificate: derivations of all rewriting rules from the defining relations.

#	Rule	Proof
1.	ac² ⇒ a	[2]
2.	b ⇒ a²	[1]

# abc:aa=b,acc=a ac/b - -
acc=a
b=aa

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