COMMENTS

It is believed that Pi is normal in every base b. This would imply that the expansion in base 26 (see A224750) or base 27 (this sequence) contains any finite string of text (e.g., the complete works of Shakespeare) infinitely often. See Example section.

See A000796 for a list of sequences giving the expansion of Pi in other bases.
