#104 ⟨a, b, c | ab=a, acc=1⟩

Properties

Sum of relation sides is 6
Infinite non-cancellative non-commutative monoid
Element a has infinite order
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ b = a and a ⋅ 1 = a, however b ≠ 1
Not right cancellative, because right multiplication by c² is not injective:
- c²a ⋅ c² = c² and 1 ⋅ c² = c², however c²a ≠ 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.	ab ⇒ a	[1]
2.	ac² ⇒ 1	[2]

# abc:ab=a,acc=1 abc - -
ab=a
acc=1

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