The code might be useful to somebody, so I will include here. It is about 15% faster than the "60 classes" code described in the posts above. It also eliminates the restriction that the starting q be a multiple of 420. The version with 4620 classes would be slower because of overhead (hey! pari is not mfaktc!).

Somebody can use it for understanding how mfaktc works, or for TF-in small exponents which are outside of the mfaktc range (again, there are much faster programs there outside, this is not for "production" purposes).
