A098322 Recurrence sequence based on positions of digits in decimal places of Catalan's constant, G (often also called K). 9

%I #11 Jul 12 2015 19:49:38

%S 0,16,48,101,421,2374,7728,9449,17685,83666,71168,128130,555251,

%T 412816,271385,1111695,1910101,11633401,14851698,9668058,43227391,

%U 159078942

%N Recurrence sequence based on positions of digits in decimal places of Catalan's constant, G (often also called K).

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

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

%e 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.

%Y Other recurrence sequences: A097614 for Pi, A098266 for e, A098289 for log(2), A098290 for Zeta(3), A098319 for 1/Pi, A098320 for 1/e, A098321 for gamma. A006752 for digits of Catalan's constant.
