#6652 ⟨a, b, c | aa=1, abacb=b⟩

Properties

Sum of relation sides is 8
Infinite non-cancellative non-commutative monoid
Element ab has infinite order
Not left cancellative, because left multiplication by b is not injective:
- b ⋅ acab = b and b ⋅ 1 = b, however acab ≠ 1
Not right cancellative, because right multiplication by b is not injective:
- baca ⋅ b = b and 1 ⋅ b = b, however baca ≠ 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
