#14383 ⟨a, b | aaaa=b, aabbb=a⟩

Properties

Presentation has sum-of-sides 11
Isomorphic to ℕ_{(14 = 1)}
Finite commutative monoid with 14 elements
Commutative Gröbner basis: ⟨a, b | b¹⁴=b, a=b¹⁰⟩
Not cancellative, because multiplication by b¹¹ is not injective:
- b¹³ ≠ 1
- b¹¹ ⋅ b¹³ = b¹¹
- b¹¹ ⋅ 1 = b¹¹
- Cancellative quotient is isomorphic to ℤ₁₃
Grothendieck group is isomorphic to ℤ₁₃
Group of units is isomorphic to ℤ₁
2 Archimedian components:
- 1, b

Element profile

2 idempotent elements:
- 1, a¹³

Complete rewriting system

Format:	Pretty Plain
Word to reduce:
	Tips: Lowercase letters stand for generators. Spaces are ignored. Numbers repeat the previous letter, e.g. `b90`.
Reduction strategy:	Leftmost Rightmost
Path to normal form:	1 1

Reduction order:
- Left-to-right recursive path with deg(a) = 0; deg(b) = 1

a¹⁴ ⇒ a
b ⇒ a⁴

# ab:aaaa=b,aabbb=a a/b
aaaaaaaaaaaaaa=a
