ok I solved this problem...

I am really wondering tho, why H(1000), H(1 000 000), and H(100 000 000) all look so similar... Can anyone explain? feel free to send me private message.
This question would be better asked in the solutions thread for this problem on the main site.

I have hesitated for almost a year to make this comment but, in my experience,
PE.net, years ago, used to offer GR8 Give and Take re solutions but...

Could someone explain how to use inclusion exclusion to speed up the solution? I get the principle behind it, but I cannot figure out how to get the formulas that actually give the counts for the numbers that are divisible by a prime number and are also congruent to 2 (mod 3).
That's a pretty simple, humble question, with no response in almost a year...
I've asked questions on solution threads myself and
Never gotten an answer... I have gotten
GR8 assistance via PE.chat PMs...

I don't think people often return to the solution threads. What I've done in the past is ask the question in the solutions thread, then post a message in these forums directing people to the question.
