[Richard Mathar]

The conjecture concerning the sums of odd prime divisors of n arising in
http://list.seqfan.eu/pipermail/seqfan/2011-June/015003.html
can be verified for all cases where n has at most 3 distinct prime divisors.
I generated a script that intends to show why this is correct in these
simple cases, http://www.strw.leidenuniv.nl/~mathar/progs/a000593.pdf .
