A098321 Recurrence sequence based on positions of digits in decimal places of gamma, the Euler-Mascheroni constant. 10
0, 11, 233, 223, 1080, 2631, 19161, 318674, 269389, 609124, 97349, 125496, 2611514, 6766458, 2093818, 4312197, 4284994, 7170002, 567295, 234495, 1574091, 1722475, 6848664, 777039, 637036, 1367169, 8195403, 3747746, 21147798, 2053675, 6009248, 12095, 312755, 1205372, 15773902, 139394774, 169096914 (list; graph; refs; listen; history; text; internal format)

LINKS

Table of n, a(n) for n=0..36.

FORMULA

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

EXAMPLE

So for example, a(2)=11 because 11th digit of gamma after decimal point is 0.

a(3)=233 because 233rd decimal digit of gamma is where 11 appears, a(4)=223 because 223rd to 225th digits of gamma form "233" and so on.

CROSSREFS
