COMMENTS

The number 7 finally appears as a(32344); 6 appears as a(?). - T. D. Noe, Sep 13 2012

EXAMPLE

a(3) = 5 because 5 is the first digit to appear 3 times in the decimal expansion of Pi = 3.141(5)926(5)3(5)... - Bobby Jacobs, Aug 30 2017

MATHEMATICA

nn = 1000; t = {}; d = RealDigits[Pi, 10, nn][[1]]; dCnt = Table[0, {10}]; cnt = 1; Do[b = ++dCnt[[1 + d[[n]]]]; If[b == cnt, AppendTo[t, d[[n]]]; cnt++], {n, nn}]; t (* T. D. Noe, Sep 13 2012 *)
