%N First digit to appear n times in the decimal expansion of the Euler-Mascheroni constant gamma.

%C If the 0 before the decimal point is not counted, then a(1) = 5, a(10) = 6, and a(18) = 4.

%e a(3) = 5 because 5 is the first digit to appear 3 times in the decimal expansion of gamma = 0.(5)7721(5)664901(5)...

%Y Cf. A001620, A096567, A195138, A195139, A195141, A195847.
