#349 ⟨a, b | aaaabaa=a⟩

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 ⋅ a³ba² = a and a ⋅ 1 = a, however a³ba² ≠ 1
Not right cancellative, because right multiplication by a is not injective:
- a⁴ba ⋅ a = a and 1 ⋅ a = a, however a⁴ba ≠ 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.	aba² ⇒ a²ba	[3]
2.	a⁵ba ⇒ a	[4]

# ab:aaaabaa=a ab - -
abaa=aaba
aaaaaba=a
