Talking Schrödinger numbers (prime and composite in the same time)

Edit: Mod note: This thread splits from the "predict the 52nd mersenne prime". Sorry for forgetting to add the note.

He said "this is the number", he didn't say it's prime.

According with past information from his posts, this is either "not a prime number", or a "Schrödinger's cat number". It can be prime and not prime in the same time until somebody (if possible, somebody else) opens the box tests it.

The PRP is ~45% complete on this so I guess it's "Schrödinger's kitten" for now. After it completes we can debate about how many GEC errors can dance on the head of a pin.

So, he succeed in corrupting convincing you?
And you did 2^85 for it? Haha.

I can't believe these trolls people still get traction!

We say in our language "Some idiot throws a stone in the lake, and a lot of wise men work so hard to take it out."

When completed, an M852348659 PRP test may be the highest yet, and it takes about 16% less effort than Laurv's LL & DC combination on M666666667. https://www.mersenne.org/report_ll/?...exfactor=1&B1=
https://www.mersenne.org/report_prp/...exfactor=1&B1=
Plus it provides the bonus of progress toward completing testing of every predict Mxx guess or dubious claim of primes in the forum threads, refuting unjustifiable claims.

Today is the two year anniversary of discovery of Mp51*.

But mine looks nicer (and I chose it by myself, nobody fed me with it)

Patience and commitment are powerful.
I got myself a list for the remaining exponents, the blue highlighted numbers have already been half gone.

I already knew M103,347,113 and M103,374,113 were composites, my group was having fun and didn't hook up to the Mersenne server in every location. Kriesel already tested 103,305,173

This exponent was just taken out of my list -

This is not a thread to publish list of exponents that you think might be prime. Stick to the rules about posting guesses.

Do the 2 suspected results prevent Kriesel from reserving new exponents in the same category?

(Offtopic, no M52 guesses)
Those were gpuowl v7.1 results, so manual assignments. PrimeNet treats all manual assignments as one heap (presumably one virtual computer), regardless of how many gpus or systems they came from. That's what I see in assignments reports and results reports, cpus reports etc.

https://www.mersenne.org/thresholds/ says thresholds pertain to a computer, not to a user account.

The issue I had with being unable to reserve some 54M LL DC was on an i7-8750H running primenet-connected prime95 v30.3b6. That has over 11,500 GhzD credit (6670 in past year).
Its reliability & confidence figures in the detailed cpu report are 0.99 and 10 respectively; 33 work units in the last year.
But 54315733 reserved ok on another system. (Dual-12-core Xeon)

What's the minimum exponent size for PRP?

I have 2,318.3 GHz Days now and what assignment category am I in now?.
