For instance when I discovered that 8022581057533823761829436662099 was a palindrome in both binary and ternary, a Google search assured me that (probably) nobody had ever noticed this fact before.
It has been in the OEIS for ever: did you try searching there? Just enter 8022581057533823761829436662099 in the search window and you get https://oeis.org/A060792 Best regards Neil Neil J. A.

I've worked on at least two problems in the past five years that I couldn't find anything about previous work on, even when I used to have access to the MathSciNet database. I did eventually conclude that they hadn't been addressed before by asking several experts in the areas they fell in. (In these cases, they didn't straddle several areas.)

Meta-problem: Find a problem that doesn't generate anything searchable. Not sequences, not large integers, not unusual real numbers, not even unusual keywords. Bonus points if it's not obvious what, if any, existing branch of math it belongs to.
