2·41 Posts Thanks Ed, I really hope the new pairs are useful, and would love to hear how they are useful!

In the future I'd like to post the pairs list more often, but without creating a new post each time. Is there a way to create a sticky post I can update, or a link to the file I can update? The file with each pair factored takes more work so will be less often.

This looks like it is just outside the range of one of my searches for (1+2*I)^2 *4 factors. Will try to rediscover it!

I'll add these to my list, have also found a number of others since my last update. I suspect most of those Paul found and I missed are due to the factors being beyond the limits of my current search, so it's good to have a search very different from mine! Please keep an eye out for any which a) Don't have 1 or -I as the unit factor; or b) don't have 1+I, 1+2*I or 1+ 4*I as one of the factors I suspect b) will be found eventually (similar to regular amicable pairs not divisible by 6 or even scarcer not divisible by 30) a) I suspect is true, maybe there is a simple proof?

2·41 Posts Thanks again for the updates Paul and Jean-Luc! Have just updated my list with your pairs and a few new ones of mine which takes it to 943 pairs. Have made this 7a, 8 will be at 1000 or more!

As always, any errors, omissions or other problems please let me know!
