Are you asking how does Prime95 do the calculations to check if a number is prime? Or are you asking how can you use Prime95 to check a particular number?

If you want to know the basics of how it does the testing here:
https://www.mersenne.org/various/math.php#lucas-lehmer

If you want to test a particular number:
First check PrimeNet to see if it is assigned. Use this URL and replace the part it red with the number you want to know about: https://www.mersenne.org/report_exponent/?exp_lo=81184969&full=1
If it is not assigned, then go into the Advanced menu on Prime95. Select test, then enter your number. Make sure that the exponent that you try is prime first. Mersenne Primes need to start with a Prime exponent.

If you are more comfortable in another language, you may want to post your question in a different language. We have people that speak a number of different ones.

We think he is asking how to chose an exponent to be sure that the mersenne number given by the respective exponent is prime, when tested with P95. If anybody know the answer, please enlight (why is this underscored in red??) us too..

Because the English word is enlighten. I figure this is a joke, but a bad one to make.

Non sequitur. It has nothing to do with what I said (and with the subject of the thread, by the way). That is an English word, yet, it is underlined by the parser. It doesn't matter that your grandma used it more than you do. The rest is just silly talk (on both sides, me and you). For me it was a joke, you can see in my former posts that I do this repeatedly, (for example "primality" is also underlined), it is because we (humans) always like to show the straw in other's eye (i.e. the fact that the parser is not perfect) and in the same time it is a kind of silly "pride" that I know some words that native people don't. As a former Scrabble player, I learned "word lists", many words I know they exist, but I don't know, or I only guess their meaning. But it seems you took it very seriously and you still have a fixation to prove me wrong ... Whatever...
