For the 1st one, its easy to see that so its definitely not prime.
Also (from observation)
You can also construct a new pseudoprime N using the proposition:
Let b >= 2 (where b is the base of this pseudoprime) and p an odd prime where p does not divide b(b-1)(b+1) then
If someone could review this and check for correctness, that would be great! :)
Edit: it works fine.
