@Aillas: I've attached a Linux Makefile for your GitHub repositories. It's made for AliMerge, but it can be adapted to SeqInfo by changing line 4. Add them as simply "Makefile", with no extension.

I think the trick is to treat the 2 mod 3 in conjecture 2 not as an actual 2, but as -1 mod 3. That means you'd use 6 mod 7 for conjecture 10, giving you the prime 3121 as the one preserving the 13.
