Re: FLMTA Prize #1: S(n)=0 & n>(phi(x)*phi(y)*phi(z)/8) > ten bucks



If n_min > lcm(phi(x), phi(y), phi(z)) / 2* gcd(phi(x),phi(y),phi(z)),
you win. Now that is a pecuiar expression.

What a mess. I forget to say the only value for n that is of interest
is the *lowest* one. If any of you are inconvenienced by this, just
post the obvious, I'll fork over the tenner, and I'll work hard on
FLTMA Prize #2.
Sheez. I thought it was obvious, but I didn't say it!

x^n + y^n = z^n, but there won't be, because FLT is proved. There would
also be x^p + y^p = z^p but that is part of another problem.
Now for any x,y,z with gcd(x,y,z) = 1 and x<y<z<(x+y), there is a
series
S(n) with 0 <= n, defined as
(x^n + y^n) mod z +
(z^n  x^n) mod y +
(z^n  y^n) mod x
and this series isof interest to those interested in random number
generators, and a few interested in FLT.
Now, I think I have got an upper limit on n  S(n) = 0. It's
phi(x)*phi(y)*phi(z)/8. Why 8?
'Cause phi is always even for any nonsmall number, and there are three
terms, I guess... 2^3 = 8. Hell, I don't know. It just seems to work
out.
I've tested every x.y.z with gcd(x.y,z) =1 and x<y<z<(x+y) up to 41.
Maybe I missed one and you can score easy!
Run it up as high as you like....or can.
If you can prove that's not the right upper limit, or give a
counterexample, then good on you, hope you had fun, you'll be
recognized here when you post, and the first posted counterexample in
news:sci.math gets ten bucks from me by check, promptly, with my
thanks.
Since we'd have to all agree on a proof, I can't offer a prize for a
proof. Sorry. :(
Have fun with it! :)
Gawd, I hope I got it right when I wrote gcd = 1 instead of pairwise
coprime.... We'll see.

Yes, phi is Euler's phi, not the golden section.

how is that a series?... phi is the golden section,
or the totient function?
