So if someone recommends you to rent a milk truck if you want to move more than ten thousand liters of milk, you would still use a truck to transport milk if you go to the supermarket and only buy a gallon?

Even though Mersenne.ca offers individual recommendations for any size exponent in reach?!

Finally found another factor between 2^75 to 2^76, the very long "No Factor" chain stopped at M168211523, at least my September won't be empty handed.

There have been triple digits of M168,***,*23 unfactored up to 2^77 - https://www.mersenne.ca/status/tf/0/20210201/4/16800

By the time I acquire the next PC, I should be able to manually pick any of them with only TF 2^77 to 2^78 unfinished.

So you are closer to proof that none of your magic numbers are prime. The sooner we can put a stake through the heart of this zombie.

Deal with it.
It would be funny to use chalsall's phrase to answer PhilF's previous post. The best way is to find the final answer which only the time will tell.

The long UncWilly drought has been well extended into M106M and expect to grow +1M larger every 2 months. Both of his eyes may stick out longer than his feet if the oasis really is found inside M168M.

New PRP Ready Exponents since 09/11/2021: M168037423, M168121423, M168217123, M168316123, M168612823, M168624823, M168634423, M168731923, M168931123.

Note: I already took M168620423 for PRP test myself.


PRP-Ready Exponents reached between 08/04/2021 and 09/11/2021: M168020323, M168133123, M168175123, M168207223, M168221023, M168227023, M168922123, M168932123, M168934123


Previous PRP-Ready Exponents: M168314323, M168412723, M168424723, M168479323, M168704323, M168779323

You will find an appropriate number of factors and get the biggest bang for your money. Also, doing so will allow any newer hardware do more of the heavy lifting. This is part of the strategy that has been employed in some other ranges.
Depending on the GPU of the PC owner, anyone who owns Nvidia Geforce 3060 Ti or better will prefer TFs to 2^79. The main reason why Zhangrc wants to bring some of the wavefront exponents to 2^77 regardless of the GPU72 recommendations to only 2^76. The P-1 bounds should definitely be larger if it comes to Intel Core-i9 12900k with DDR5 memories and PCIe5.

I'm aiming for 3060 Ti for the moment since the GPU prices are still pretty high unless a store has 3070 Ti on sale with at least 20% off.

By the time the wave front makes the landfall in that range as a Cat 1, M168M should drop down to Cat 3. Too bad there's not a Cat 5 to match the hurricane levels.

But what if it's composite? What do I get out of the deal?
Since you mentioned Radeon VII not Radeon VI, I finally get the point. You'll want to buy at least 1 AMD Radeon 7900 XT in Q4 2022 before willing to run the PRP tests in the M168M range. The wave front should be around M117M at that time.

Very confident that UncWilly's drought will still be there by Nov 2022 to fulfill the prediction of the longest gap of 1400+ days.

I wouldn't call any GPUs in the family of Geforce 30*0 Ti a pigeon on the roof. It has to be at least Geforce 4080 with a 5nm micro structure which is capable of finishing the TFs of 2^81 to 2^82 of M168,***,*23 within half a day.

There's so far not a single M168,***,*23 which has no factors under 2^76 and has a factor between 2^76 to 2^78 that cannot be found with the standard P-1 bounds recommended by GPU72.

M168607223 has a factor between 2^77 to 2^78 and was actually found through P-1 beforehand.

At least my CPU is able to finish more P-1 everyday, so that part goes faster than ever before.

Looks like I'll eventually be able to put M168779323 into Kriesel's hands, best if around the Christmas time.

You took a comment from a different thread an parked it here out of context. And then went on a tangent. That is not a way to win friends.

It's very possible the last 2 digits of the next hidden Mersenne Prime is 4Ɛ when written in the dozenal base, I'll have to check every M168,***,*23 exponents, see which candidates match this characteristic.

Also in base 5 dozens, the dozenal 4Ɛ enders(as a regular number) frequently come directly 1 less than a very composite number. There is indeed already 1 existing Mersenne Prime(Z1053Ӿ84Ɛ) on the discovery list that has the dozenal 4Ɛ ender(as an exponent of a Mersenne number). When I have the time and chance, I'll run the PRP tests on Z4843804Ɛ along with its 2 brothers(Z4859044Ɛ and Z4861454Ɛ), I hope 1 of those 3 turns out to be the real hidden Z#44.

Anyway, I'm not fully awaken at the moment.
