The sum of the first n odd integers is n 2. 1 + 3 + 5 + ... + (2n − 1) = n 2. Animated 3D visualization on a tetrahedron. There are several recursive methods for computing square numbers. For example, the n th square number can be computed from the previous square by n 2 = (n − 1) 2 + (n − 1) + n = (n − 1) 2 + (2n − 1).
The term was coined in 1920 by 9-year-old Milton Sirotta (1911–1981), nephew of American mathematician Edward Kasner. [1] He may have been inspired by the contemporary comic strip character Barney Google. [2] Kasner popularized the concept in his 1940 book Mathematics and the Imagination. [3]

Sagan gave an example that if the entire volume of the observable universe is filled with fine dust particles roughly 1.5 micrometers in size (0.0015 millimeters), then the number of different combinations in which the particles could be arranged and numbered would be about one googolplex. [8] [9]

The name of a number 10 3n+3, where n is greater than or equal to 1000, is formed by concatenating the names of the numbers of the form 10 3m+3, where m represents each group of comma-separated digits of n, with each but the last "-illion" trimmed to "-illi-", or, in the case of m = 0, either "-nilli-" or "-nillion". [17]
f ω (n) = f n (n) > 2 ↑ n – 1 n > 2 ↑ n − 2 (n + 3) − 3 = A(n, n) for n ≥ 2, where A is the Ackermann function (of which f ω is a unary version) f ω+1 (64) > f ω 64 (6) > Graham's number (= g 64 in the sequence defined by g 0 = 4, g k+1 = 3 ↑ g k 3) This follows by noting f ω (n) > 2 ↑ n – 1 n > 3 ↑ n – 2 3 + 2, and ...
