If you can find a polynomial of degree at most 7 (and at least 4) with coefficients all of which are smaller than, say, 9 digits and a corresponding root modulo N (where N is the 217digit number (or the 195digit number)) then we could run SNFS on it.

For cases where we can find such a polynomial, is the feasible range then same 180240 digits quoted above? Or would such a "found" polynomial be less effective, so that the practical range is something between these ranges?
