    There’s a 9 repeating 6 times in there which I’d think is a pretty rare occurrence in pi. I wonder what the longest occurrence of a repeating digit is.

      Pi is infinite so every combination/string of numbers is in there, if we calculated enough you could find a billion 2s next to each other

      You can look through the first trillion here

      Though it’s a bunch of downloading

        Not necessarily. It could just become a series of 1’s repeating forever. Nothing would require it to contain all strings of numbers.

          If that happens in a number, then it is rational. Pi is not rational, so that will never happen in pi.

            Take a look at 0.101001000100001… This number is also non-repeating, but obviously doesn’t contain all numbers with finite digits.

            The property you’re looking for is called to be a normal number. Pi is assumed to be one, but it hasn’t yet been proven.

            However, in a sense this is an unremarkable property as almost all real numbers are normal. :)

              but obviously doesn’t contain all numbers with finite digits.

              I was just claiming possibility because we haven’t calculated the infinite string
