Yup, just noticed that:-

$ ../dodeca20 50 717000000000000 720000000000000
You can also find the k n values in results_dodeca.txt file ( These are 3-probable primes )
n=50, kmin=717000000000000, kmax=720000000000000, version=2.0
Starting the sieve...
Using the first 8 primes to reduce the size of the sieve array
717083008036395 50

The sieving is complete.
Number of Prp tests=213
Time=6 sec.

This proves that double checking is useful (and necessary!).

Also got:-

$ ../dodeca20 58 10000000000000000 100000000000000000
You can also find the k n values in results_dodeca.txt file ( These are 3-probable primes )
n=58, kmin=10000000000000000, kmax=100000000000000000, version=2.0
Starting the sieve...
Using the first 11 primes to reduce the size of the sieve array

Status: 6.0 percentage of the project is complete. Time thusfar: 990 sec.

Yes, that's in the range 10000T (1E16) to 100000T (1E17).

Sorry Kosmaj, this was in your reserved range, I was supposed to be testing n=55. Should teach me to check things more closely.
