#18993 ⟨a, b | aab=b, abaaaa=b⟩

Properties

Sum of relation sides is 11
Infinite non-cancellative non-commutative monoid
Element a has infinite order
Not left cancellative, because left multiplication by b is not injective:
- b ⋅ a⁸ = b and b ⋅ 1 = b, however a⁸ ≠ 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

#	Rule	Proof
1.	ba⁸ ⇒ b	[4]
2.	ab ⇒ ba⁴	[3]

# ab:aab=b,abaaaa=b a/b - -
baaaaaaaa=b
ab=baaaa

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