 OFFSET 1,1 COMMENTS From M. F. Hasler, Mar 21 2017: (Start) Positions 0,1,2,... correspond to digits 3,1,4,... as in the search engines and most related sequences, while some sequences, e.g., A049522, use indexing starting at 1. Consecutive numbers indicate that there are more than eight '7's in a row, e.g., at positions 24658601, 1136093224, 1387894932,... start runs of nine '7's. The first of these is also A049522(9)-1 = A049523(9)-1. (End) LINKS Dave Andersen, Pi-Search Page James Taylor, Irrational Number Search Engine Eric Weisstein's World of Mathematics, Pi Digits.
