I was trying to add a column of numbers in LibreOffice Calc the other day, and I ran out of fingers. Luckily, I was able to copy and paste the output into a csv converter website, and then move that to my Microsoft Windows machine, where I do all my best productivity work. Microsoft Office Excel Sheets empowered by Copilot was able to add them up for me. (17 was the total, in case you wondered)
Hmmm, could be numbers k such that phi(k) divides k+1, where phi is Euler’s totient function or perhaps numbers k such that every base-4 digit of k is a base-6 digit of k? Quite the puzzler.
