%N Least even k such that sfdf(k-3) > sfdf(k-1) >= A050376(n), where sfdf(n) is the smallest Fermi-Dirac factor of n (A223490).
%C a(n) is a Fermi-Dirac analog of A242719.
%e If k is even such that k-1 is either 1 or in A050376, then k cannot be required. Thus, if n=2, then k=2,4,6,8,10,12,14 are not required, while for k=16 we have sfdf(16-3) = 13 > sfdf(16-1) = 3 = A050376(2). So a(2)=16.
%Y Cf. A050376, A223490, A242719.
