With a conjectured k of 14, this conjecture is proven.

Sierpinski bases 935 and 1013
 

These are the last three with a conjectured k of 14. I'm reserving them.

Oops, I just realized that I put this in the wrong thread. Could someone please move this to the correct thread.

Edit: Moved

You only listed 2, so I'm assuming you meant S740, S935 and S1013.

I'm only doing two today and the other will be for tomorrow (if someone doesn't beat me to it). I don't want to break the rules. :smile:
