public static int nthTriangle(int n)
                       throws ArithmeticException
```
    Calculate nth triangular number. This is used to calculate the number of subLists for a given list variable of size n. To be able to use int arithmetic to calculate the triangular number, n must be less than or equal to HIGHEST_SAFE_N. If the n is higher, the method throws an exception.
    
    Parameters:
    
    n - size of the triangle (the length of its side)
    
    Returns:
    
    nth triangular number
    
    Throws:
    
    ArithmeticException - if n is higher than HIGHEST_SAFE_N
