does it repeat? or is it like pi? -- oh the wiki says its an infinite sequence. that might be handy for generating pseudo random numbers i guess. i wonder if theres a function that generates the correct digit at position n? doh, wiki says theres a recursive formula for the i'th term.
it doesn't repeat at least:
> More generally, the sequence is cube-free, i.e., has no substring of the form w w w with w some nonempty finite string.
