Default Octoproth Reservation Thread

First goal of the project is: get all numbers <= 1000 up to 1000T
Second goal of the project find an octoproth for the numbers in the range 233 <= <number> <= 300 23 to go!

How it works.

Find an n value where no Octoproth has been found, and check the posts below to ensure that noone else has reserved it. Post in this thread to say you are reserving that n. If a previous kmax is provided then start your search from that point. If not you must start from 1. Ensure you check the entire range from kmin to kmax, don't just stop if the program finds one octoproth.

When you have finished with your range make another post here with the following information:

n_value (kmax) forum_name octoproths_found

i.e. I took n=230 up to 10000000000000 and found 3 Octoproths.

230 Greenbank (10000000000000) 3 found

Secondly, submit the results_octo.txt file to cedricvonck@skynet.be

This thread will be maintained and updated by the moderators.

Attention !!! Some k's will take a very long time to process !!! Attention !!!
Search in small ranges 100T to 200T at once.

By user Jasong:

I convinced someone into making a program to facilitate the making of the octoproth batch files. The file is called jasong_cmd, but you can change the name of the file using the Properties tab(right click, then select Properties). The format to run the file is jasong_cmd <n-value> <beginning k-value> <ending k_value> <range of k> >> <filename>

Code:
jasong_cmd  666 1000 1500 50 > test.bat
A few comments: When you enter the k values, assume your numbers will have 12 zeroes attached to the end of them, so 1 would turn into '1000000000000'.



As requested by the forum administrator, please do not post the result files to the board but mail them to me.
As indicated in this post.

Thank you
