No, not really. There are size issues as T needs to be roughly equal
to N^2 for 50% probability with a=1, which I knew from the surrogate
factoring research, but kind of forgot.

You should have seen that in your results where as N gets bigger it
takes longer and longer to get an answer, kind of like there are zones
where you CANNOT get the answer, as there are zones where answers are
far less likely.

What I see in my results are pairs of periodic impulse functions of
periods
equal to the pairs of primes in N. Intersections of the two functions
show
where solutions exist and the whole thing has a period of N, plus
reflection symmetry

In your solution yesterday for X^2 = 2 mod 161, you used
f1 = 143 and j = 111

143 divides 2q + jN evenly ONLY at the places where both
a solution to X^2 = 2 mod 161 and a factorization of 161 exist.
(Your right - it looks elegant)
There are 4 such places at intervals of 161.
Of any such group of 4, only 2 give nontrivial factorizations.

I assume thats the source of your 50% probability claim.

Is it significant that f1 = 143 is itself a solution to X^2 = 2 mod
161 ?

Is it significant that j = 111 is related to another solution of X^2
= 2 mod 161:
X = 74 via 74 * 3 / 2 = 111 ?

What twilight 'zone' do you exist in where anyone accepts this
nonsensical gibberish?

Are you delusional?

You are totally zoned in on the women and don't want to do the math.

Shame on you!

I worked backwards using f_1 = 3 mod 7 and f_1 = 5 mod 23, which gives
f_1 = 143 mod 161.

> I assume thats the source of your 50% probability claim.

That seems more and more to me like a guess having to do with
quadratic residues being so significant.

But I'm looking back over a year and it all gets fuzzy. My past self
seemed to think that was the probability, but I'm not really sure any
more why.

> Is it significant that f1 = 143 is itself a solution to X^2 = 2 mod
> 161 ?

Two key underlying surrogate factoring equations are:

f_1 = ak mod p, and f_2 = a^{-1}(1 + a^2)k mod p

where with N, p is a prime factor of N, and those equations are not
necessarily valid for N, but still end up being valid for some prime
factor of it. I've been using a=1, so if they are valid for both,
then yeah, k will equal f_1, and for the prime case you'd see that is
always the case.

Using k = 3^{-1}(f_1 + f_2) mod N, though works regardless though it's
true mod p, as well, of course. I thought that was cool as I just
jumped to mod N from mod p, and it's not always true that everything
carries over.

I don't know. These surrogate factoring equations can be interesting
to unravel as you're always dealing with two factorizations.

Your pulling information out of one from the other or vice versa so
there are all these underlying mathematical relationships where they
connect to each other.

Hey, to me it's interesting mathematics and easily qualifies as of
interest for "pure math" reasons which I toss out because there are
posters who keep taunting about factoring a large number.

But the underlying mathematics is really this connection between TWO
factorizations, so who knows what you might see playing with it
enough. I suspect some of what you might see would look like
interference patterns.

IN any event, success with a=1 depends no certain things. You might
find more success with a=2. Also T can be even or odd. I often use
odd T, just because. (I kind of don't like messing with a lot of
factors of 2.)

I'm guessing now for various reasons that the probability of success
with a>1 is roughly: ((a-1)/a)*(50%).

With a=1, I'm guessing you have 50% probability with T>N^2, but it
still may work with smaller T but I'm not sure what the probability is
(lots of competing factors come into play).

This may be a significant result, worthy of investigation.
I postulate that for any positive integer, 50% to be an upper-bound on
the probability of it being prime, and thus a possible prime factor from
James' factorization techniques. It's amazing.
