My favorite integer sequence

And there it is: C:≈0.923307±0.000001, where C is 1/a_1 as I defined it.

That abstract looks familiar. I'm pretty sure it's the same paywalled paper I linked to before. It was written the year I was born, so it just seems a shame that there's still such a hefty fee to access it (over $40).
Too bad you can't find the original paper; $40 is pretty steep. I'm not in a math program, so I don't think I have access to the local university library without a student ID; never tried.

How large a value of "k" have you calculated A(k) for, and how long does it take? I know you were working on a logarithmic algorithm in terms of memory requirements... but I thought the time was still proportional to "k". I didn't follow where you got to after that. Your chart shows 2^240 which is pretty big ... impressive!

Also, I think , but I'm only using k=800,000, along with some questionable accelerator techniques to estimate the function, also assuming that it converges to a particular periodic function which I posted earlier, fairly quickly.



Then I took the inverse of the zerocount function at 16, 15.5, 15, 14.5. 14, 13.5, 13, 12.5 and averaged all of the alpha_1 values with a binomial weighting. I estimated the error term by varying the starting point from 16 to 15.5. Of course, it may be an illusion that this sum converges to alpha_1... I could try more terms though since I'm only using k=800000
