Unhappy in choosing prime sequence :-)

[pepi37]

Whatever sequence I choose I fail to find big prime (above 1.2M digits)
So right question is- to change sequence when I reach some point, or to stick with few and be patient
What is your suggestion/advice ?

Either you can look for light or heavy k sequences. Heavy has the advantage of the tests not taking as long. You might also consider a fixed n search.

how are you choosing the sequence? is it a polynomial , a recurrence, a special form like Mersennes? have you narrowed down the properties that may be stopping it from working ?

Your question contains the answer.
So the answer to your question is: yes.

Primary I take sequences where K is 4 :)
So for last one 4*53^n+1 nash weight is 585. Also there is 4*155 and 4*212 and so on. But also there is few sequences of base 10, where also ( regardless much more weight) Ihave no luck :)
So I take various bases and various K :)

Gary told me in one message that sequences I choose is ordinary much harder to produce prime then "ordinary one" :)
So that may be price "I pay" :)

Crystal clear answer

What else to do : make deeper sieve, and wait

So it must be only good answer :)

This reminds me of a Mork and Mindy episode where Mork goes to a bank to open an account:

Teller: Name?

Mork: Mork,

Teller: Is that your first name or last name?

Mork: Yes.
