The paper by Luca in http://oeis.org/A007955 multiplicative perfect
numbers (n) such that A007955(n)=n^k for some positive k. Is this sequence
of multiplicative perfect numbers the same as http://oeis.org/A164514 ?
If yes, this should be mentioned in A164514, if no, maybe this
ought become a new sequence...
