For n=82, there are 4 k's < 10^12
42290329515 481562533725 549711786105 624949113615 EDIT: No luck for n=81 for k < 10^12. This n was a "low weight" one compared to n=82 Last fiddled with by axn on 20050409 at 10:41

109
Checked 109 last night, one candidate that fell at the last hurdle, unlike the horse I chose for the Grand National, which cost me a tenner when it fell at the first!
Will do 108 tonight. Regards Robert Smith

Results for n = 97 (after 65% completion to k<10^13)
1926973493115 2212009461375 2412877121565 5647136892825 @ltd  see the attached Pascal source code  Its not much. You'll have to modify the constants in the program and compile (you can use FreePascal compiler). I plan to later clean it up and make it accept command line parameters Last fiddled with by axn on 20050411 at 09:05

Uploading the latest version of the sieve along with the executable. The output needs to be redirected to some file. The resulting file can be further sieved using NewPGen.

108
Ran 108 last night to 10^11, and no octos, sadly to say.
Axn1, will you be writing your code in a windows executable? I would certainly be interesting in devoting some raw computer power to take it further. Regards Robert Smith
