Suppose we do:
```
l := [44, 178, 412, 746, 1168, 1669, 2260, 2941, 3712, 4573, 5524, 6565]
e := guess(l).1
```
Now we have a recurrence, with its 'n as its variable. Now if I do this:

Sympy can integrate only very simple integrands containing li(z):
In [3]: li(x)
Out[3]: li(x)
In [4]: integrate(_, x)
Out[4]: x*li(x) - Ei(2*log(x))
In [5]: _.rewrite(li)
Out[5]: x*li(x) - li(x…

The motivation for this ticket is that the documentation for

didn't mention very explicitly the different algorithms (it omits 'fricas', for example). The documentation that appe…

The relatively simple limit `sage: ((factorial(x)-1)/x).limit(x=0)` crashes silently, regardless of the algorithm.
