Some recommended sequences

schickel · 2009-03-20, 08:17

Here are some recommendations for sequences to take up:

Code:

154548  696. 2^4 * 3 c104 sz 111
553014 1111. 2^2 * 3 c96 sz 108

Obviously, the ones with the larger "cxx" values will probably decrease in value after factorization (but not if the guide is an abundant number).

Black guide sequences will usually be better than blue guide sequences.

Check here for a listing of the longest sequences.

Please remember to check the reservation thread in case someone reserves one of these....

WARNING: We're beginning to run out of immediately stable sequences, so be prepared for the sequences to rise a few digits before getting rid of the 3 (or whatever).

(recomputed from step 1 to 721 already ... clear bug in the factorization.ath.cx record)

Let's do 122892 too (I'm assuming the factorization.ath.cx page is right for this one)

10metreh: It looks good, give it a go!
