Number of stable digits of any integer tetration
Marco Ripà, Luca Onnis
In the present paper we provide a formula that allows to compute the number of stable digits of any integer tetration base . The number of stable digits, at the g…
On some nested floor functions and their jump discontinuities
Luca Onnis
This paper investigates some particular limits involving nested floor functions. We'll prove some cases and then we'll show a more general result. Then we'll count the discontinuit…
On the general Smarandache's sigma product of digits
Luca Onnis
This paper investigates the behaviour of one of the most famous Smarandache's sequence given by A061076 on oeis. In particular we first study the behaviour of two sequences (A06107…
On a variant of the happy numbers and their generalizations
Luca Onnis
This paper investigates a variant of the famous "happy numbers" sequence, given by A351327 on the oeis. First of all we'll define this integer sequence, and then we'll show some im…
Observations regarding the repetition of the last digits of a tetration of generic base
Luca Onnis
This paper investigates the behavior of the last digits of a tetration of generic base. In fact, last digits of a tetration are the same starting from a certain hyper-exponent and…
