Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

A098322 Recurrence sequence based on positions of digits in decimal places of Catalan's constant, G (often also called K). 9
0, 16, 48, 101, 421, 2374, 7728, 9449, 17685, 83666, 71168, 128130, 555251, 412816, 271385, 1111695, 1910101, 11633401, 14851698, 9668058, 43227391, 159078942 (list; graph; refs; listen; history; text; internal format)

LINKS

Table of n, a(n) for n=0..21.

FORMULA

a(1)=0, p(i)=position of first occurrence of a(i) in decimal places of G, a(i+1)=p(i).

EXAMPLE

So for example, a(2)=16 because 16th digit of G is 0.

a(3)=48 because 16 appears at the 48th-49th digits of G, a(4)=101 because the 101st to 102nd digits of G form "48" and so on.
