COMMENTS

Let b(n)=a(n), but with instead of a(8)=3 and a(18)=4, define b(8)=4 and b(18)=3 (i.e. otherwise same, but the values in positions 8 and 18 are swapped). The sequence b is then a permutation induced when A234743 is restricted to primes, and the indices of the reordered primes are collected: We have A049084(A234743(A000040(n))) = b(n) for all n. Or in other words, the permutation b completely determines the permutation A234743, because the latter is multiplicative. See further comments there.
