May 23, 2012 at 11:03 comment added Timothy Foo Oh, thanks very much! If there is more to say about the general case, I'll let you know!
May 11, 2012 at 17:56 comment added Gottfried Helms I'm "accepting" the answer because there has been no more activity for a long time. Your derivation is helpful anyway and I'll try to generalize it. Thanks for your input!

Dec 20, 2011 at 17:48 comment added Gottfried Helms Hmm, thank you for your input - I'll need a certain time to digest this. I was approaching the problem using little Fermat/Euler's totient function (and the connection to geometric series for the infinite case) but, for instance, was unsecure, what effect the higher fermat-quotients would introduce- they should "lift" the sums of primefactors q - but their occurences have no simple formula. Well, such effects should vanish if w goes to infinity (if their occurences are finite), but we do not know this (that was one of the main reasons, that I looked into experimental heuristics at all)
