... find no counterexample up to k < 3061 (see Jaeschke [24], Baillie, Cormack and Williams [2]). Erdős and Odlyzko [19] proved that the set of odd numbers k for which there exists a positive integer n with k2n + 1 being prime has positive lower asymptotic density in the set of all positive odd integer ...

... The iterated totient function φk (n) is ak in the recurrence relation a0 = n and ai = φ(ai−1 ) for i > 0, where φ(x) is Euler’s totient function. After enough iterations, the function eventually hits 2 followed by an infinite trail of ones. Ianucci et al define the “class” c of n as the integer such ...

... natural numbers. For example, suppose that n = 16. One could begin by adding the numbers (i.e. 1 + 2 + 3 + … + 16). However, one way to add the numbers, using the both the commutative and associative laws of addition, could be to change the order and groupings of the numbers. In our example, the fir ...
