#5380 ⟨a, b | aab=ab, baa=ab⟩

Properties

Sum of relation sides is 10
Infinite non-cancellative non-commutative monoid
Element a has infinite order
Not left cancellative, because left multiplication by b is not injective:
- b ⋅ a⁴ = ba² and b ⋅ a² = ba², however a⁴ ≠ a²
Not right cancellative, because right multiplication by a is not injective:
- ba³ ⋅ a = ba² and ba ⋅ a = ba², however ba³ ≠ ba

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.	ba⁴ ⇒ ba²	[4]
2.	ab ⇒ ba²	[2]

# ab:aab=ab,baa=ab a/b - -
baaaa=baa
ab=baa
