%N Denominator of the integral of x^n times the Cantor function, from 0 to 1.
%F I(n) = 1/(2*(n+1)) + 1/(2*3^(n+1)-1) * sum_{i=0}{n-1} (n choose i) 2^(n-i) I(i)
%e I(0) is obviously 1/2 by symmetry.
%Y A159009 gives the corresponding numerators. A095844/A095845 give the integrals of powers of the Cantor function itself.
%K frac,nonn
%O 0,1
