I recently watched a Numberphile video where Neil shows an interesting sequence of numbers. In the end, I felt a bit empty since a prime number of this kind should exist but unfortunately, we have not been able to find one for the last sequence. I wrote some code in python that if you let it run long enough it will eventually find one. I hope. I think. There might be an issue if the int is too big. A bonus sequence I coded, by accident, is the sequence of all of the digits repeating themselves until ten. For example 123456789101234... This wasn't a difficult challenge but it was definitely an interesting one. For the palindrome prime the highest I've gone to is 21 and for the most wanted 133.
