"When I've found all 86 sets that add up to 34, the puzzle invites me to continue but if I submit another it will either be a repeat of one already found or add up to a different total. So when I've found all 86, shouldn't the puzzle confirm that I've found all of them? (There are 86, aren't there?)."

"Richard, congratulations, you are correct, there are 86 ways altogether. The reason the program didn’t tell you you’d found them all was to test if you knew there were no more. The action to take at that point is to claim your trophy. I will think about changing the program so that you get affirmative feedback when all 86 have been found. Thanks so much for taking the time to comment on this activity."
