#5682 ⟨a, b, c | aa=b, abb=bc⟩

Properties

Sum of relation sides is 8
Infinite non-cancellative non-commutative monoid
Element a has infinite order
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ ac = a⁵ and a ⋅ a⁴ = a⁵, however ac ≠ a⁴

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

#	Rule	Proof
1.	b ⇒ a²	[1]
2.	a²c ⇒ a⁵	[2]

# abc:aa=b,abb=bc a/bc - -
b=aa
aac=aaaaa
