@OleksandrR. There is an obvious mathematical relationship between these functions : they are "almost" inverse, I mean e.g. : Prime@PrimePi@Range[101, 105] returns 'Range[101, 105]` , i.e. identity, but not PrimePi@Prime. There are also some issues of their internal implementations which are certainly more obscure.

An interesting observation is that Prime calls PrimePi many (namely, 1,013,381) times when given an argument of your OmegaPrime: nums = Reap[Internal`InheritedBlock[{PrimePi}, Unprotect[PrimePi]; pp:PrimePi[n_] /; (Sow[n]; True) := pp; Protect[PrimePi]; Prime[7783516045221]]][[2, 1]]; ListLogLogPlot[nums, MaxPlotPoints -> 1000, Joined -> True] gives nearly a straight line. What this means, if anything, I have no idea, but it shows at least some concrete relationship between the two functions.

@murray I gave Attributes here only for instance of what one could expect since I had checked this before and it hadn't enlightened me more.

One should certainly not expect Attributes to answer such a question, as that function deals with various general-type properties. My guess is that the only possibility beyond experimentation is looking at the documentation. And if that doesn't help, ask Wolfram tech support.

@belisarius Thank You ! I believe there is a need for Primes tag since M contains quite a good functionality in this field and there could appear many interesting and related questions.

| Mar 21, 2012 at 22:57 | comment | added | Artes | @Mr.Wizard Thanks for your support. I really have many questions but not too much time to formulate them. | |
| Mar 21, 2012 at 22:53 | comment | added | Mr.Wizard | I love the questions people come up with. +1 | |
