COMMENT
|
Two problems arise: what would be a "size 0" chunk (the 33rd digit of pi is a 0)? This has been fixed by linking the according 0 (decimal expansion of pi) to its immediate predecessor, thus leading to a chunk of 10 or more digits in the "golombisation". Second problem: what if some chunks have a leading zero? This has been fixed by the same procedure: the responsible digit of pi is linked to its predecessor, thus producing a larger chunk (this explains why the 15th chunk of the sequence is 93-digit long: the 9-digit long chunk would fit (164062862), but the following 3-digit long chunk would start with a 0 (089).
