%N Number of times the digit 8 appears in the first 10^n decimal digits of Euler's number e = exp(1), counting starts after the decimal point.
%C It is not known if e is normal, but the distribution of decimal digits found for the first 10^n digits of e shows no statistically significant departure from a uniform distribution.
