I restarted the search for primes with k = 105105.

So far I have checked up to n = 395 000 and found 4 primes:
105105*2^328791-1
105105*2^333964-1
105105*2^358832-1
105105*2^387091-1

Also regarding k=20020913, I have found another prime:
20020913*2^862692-1

I will update those k's in Prime Wiki.
