The rectangular spiral or the $n_{1} \times n_{2} \times \dots \times n_{k}$ Points Problem

Marco Ripà

A generalization of Ripà's square spiral solution for the $n \times n \times \dots \times n$ Points Upper Bound Problem. Additionally, we provide a non-trivial lower bound for the…

Congruence speed of tetration bases ending with $0$

Marco Ripà

For every non-negative integer $a$ and positive integer $b$ , the congruence speed of the tetration $^{b} a$ is the difference between the number of the rightmost digits of $^{b} a$ t…
