#5529 ⟨a, b, c | ab=c, abcb=b⟩

Properties

Sum of relation sides is 8
Infinite non-cancellative non-commutative monoid
Element a has infinite order
Not right cancellative, because right multiplication by b is not injective:
- (ab)² ⋅ b = b and 1 ⋅ b = b, however (ab)² ≠ 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

Reduction order:
- Left-to-right recursive path with deg(a) = deg(b) = 0, a < b; deg(c) = 1
Certificate: derivations of all rewriting rules from the defining relations.

#	Rule	Proof
1.	abab² ⇒ b	[2]
2.	c ⇒ ab	[1]

# abc:ab=c,abcb=b ab/c - -
ababb=b
c=ab

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