%N Leaders in the race of digits of square root of 2.

%C Next term which is different from earlier in A195141.

%e Since sqrt(2) = 1.414213562373095048801688724209698... the decimal expansion of square root of 2 starts with 1 (see A000796) hence the first leader in the race of digits is 1, so a(1) = 1. After 34 stages the new leader is 8 because the number 8 appears five times and the earlier leader appears four times, so a(2) = 8.

%Y Cf. A002193, A195141, A195835, A195844, A195845, A195847.
