[QUOTE=MyDogBuster;253229]Yes, it is useful.

Serge, did you test k=40 to n=160K also? If so, can you post the results?[/QUOTE]
I guess I can do this now.

[B]Reserving[/B] to match the S257 (k=40) to the same limit n<=160K.
(actually k=4 is going on and is at n~=300k now for the GFN search.)

S327 is done to n<=25000. Residues will be emailed shortly. Only :furious: 4 [I]k [/I] were eliminated in 10-25k range:
302*327^15260+1
1782*327^16344+1
208*327^18282+1
1228*327^22250+1
23 k remain. Base released.

I would like to reserve R392 to 50K
