Unitary Perfect Number

    I think that if UnitarySigma is replaced by Sigma then such a limit for n number doesn't exist for each k.

    Sigma^{k}(m)=n*m

Dear Seqfans,  There are very few Python programs in the OEIS.
I would like to get more - even for the simplest sequences,
and especially for all the important sequences, whenever appropriate.
