It seems that
http://oeis.org/classic/A162302 is incomplete. I get
1,
28,
29,
62,
84,
182,
230,
252,
344,
756,
944,
2268,
6710,
6804,
....
or is there something missing in the defn?
Should this simply be replaced by 28*3^n, comments removed?

if (numtheory[sigma](n)+28) mod n = 0 then
printf("%d,\n",n) ;
end if;
