Ackermann Function
The Ackermann function may be expressed using Conway chained arrow notation:
- A(m, n) = (2 → (n + 3) → (m − 2)) − 3 for m > 2
hence
- 2 → n → m = A(m + 2,n − 3) + 3 for n > 2
(n = 1 and n = 2 would correspond with A(m, −2) = −1 and A(m, −1) = 1, which could logically be added).

Famous quotes containing the word function:
“To look backward for a while is to refresh the eye, to restore it, and to render it the more fit for its prime function of looking forward.”
—Margaret Fairless Barber (1869–1901)
