#2450 ⟨a, b, c | aab=b, bccc=1⟩

Properties

Sum of relation sides is 8
Infinite non-cancellative non-commutative monoid
Element ba has infinite order
Not left cancellative, because left multiplication by b is not injective:
- b ⋅ c³b = b and b ⋅ 1 = b, however c³b ≠ 1
Not right cancellative, because right multiplication by c³ is not injective:
- c³b ⋅ c³ = c³ and 1 ⋅ c³ = c³, however c³b ≠ 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.	a² ⇒ 1	[3]
2.	bc³ ⇒ 1	[2]

# abc:aab=b,bccc=1 abc - -
aa=1
bccc=1
