%N A048673 Permutation of natural numbers obtained by replacing each prime divisor 
               of n with the next prime and mapping the generated odd numbers to 
               all integers.
%C A048673 Inverse of sequence A064216 considered as a permutation of the positive 
               integers. - Howard A. Landman (howard(AT)polyamory.org), Sep 25 2001
%H A048673 <a href="Sindx_Per.html#IntegerPermutation">Index entries for sequences 
               that are permutations of the natural numbers</a>
%F A048673 a(1)=1, a(n)=(succfactorization(n)+1)/2, i.e. a(n)=floor((A045965[ n 
               ]+1)/2)
%e A048673 a(12)=23, as 12=2^2 * 3, thus ((3^2 * 5)+1)/2=23
%Y A048673 Cf. A045965 and A048674. Permutation of A000027.
