Does anyone known whether the list in A007357, the infinitary perfect numbers
with isigma(n) =2*n, can be extended by just copying a list of known
infinitary perfect numbers from http://amicable.adsl.dk/aliquot/i1/i1.txt
into a b-file? That is, does http://amicable.adsl.dk/aliquot/i1/i1.txt
contain holes?
