#3556 ⟨a, b, c | ab=aa, cb=aa⟩

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 ⋅ b = a² and a ⋅ a = a², however b ≠ a

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

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

# abc:ab=aa,cb=aa abc - -
ab=aa
cb=aa

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