#7172 ⟨a, b, c | aa=1, abbc=cc⟩

Properties

Sum of relation sides is 8
Infinite non-cancellative non-commutative monoid
Element ba has infinite order
Not right cancellative, because right multiplication by c is not injective:
- b² ⋅ c = ac² and ac ⋅ c = ac², however b² ≠ ac

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.	a² ⇒ 1	[1]
2.	b²c ⇒ ac²	[3]

# abc:aa=1,abbc=cc abc - -
aa=1
bbc=acc
