%N A048621 Central value of p(C(n,[ n/2 ])), where p()=A001222 (prime factors with 
               multiple counting) applied to A001405(n).
%F A048621 A001222(A001405(n))=a(n)
%e A048621 n=24: the sums of prime factor exponents when k runs from 0 to 24 is 
               {0,4,4,5,5,7,6,8,6,8,8,9,7,9,8,8,6,8,6,7,5,5,4,4,0}. The central 
               value is 7, so a(24)=7.
%Y A048621 A001222, A001221, A046660, A034973, A034974.
