Direct Known Subclasses:

SolutionArrays
```
public class BaseArrays
extends Object
```
Passive data structure bundling primes/powers, modular sqrts and logP-values. Having a structure with several arrays of the same size is faster than having an array of a structure, because the former permits to exploit AVX/SSE mechanisms in Java 8.
