... number is expressed as a binary numeral. Therefore while a64 takes 6 steps, a63 would take 5 + 4 + 3 + 2 + 1 = 15 steps, naively (i.e. this is what I thought). But, if we record our work along the way and remember our answers we don’t need to recompute them. Keeping with a63 . We take 5 multiplicati ...

Riemann`s Zeta Function and the Prime Number
... Let X = {x1 , x2 , . . . , xs } be a set of s randomly chosen integers. Let P be the probability that gcd(X) > 1. Then P = 1/ζ(s). • Let p be a prime. P (xi is divisible by p) = 1/p. • P (s random numbers are all divisible by p) = (1/p)s • P (at least one xi is not divisible by p) = 1 − p−s • Probab ...

The Number of t-Cores of Size n
... Next, we describe a function from P (n) to B(n+1): this function is surjective, but obviously not injective. Let λ = (λ1 , . . . , λr ) be a partition of n, with the last k parts of λ equal to 1. Then define f (λ) by f (λ) = (λ1 + 1 + k, λ2 , . . . , λr−k ); that is, by removing the parts of size 1 ...
