Hello, Group. After reviewing an excel table concerning the pattern of mersenne exponents, I believe that the 43rd Mprime will be with an exponent in the...

Hi all, I'm using IDE 4.0 of Sun and I need to "power" some BigInteger numbers with big exponents (the integer exponent is not enough). Is there any way to do...
Faysal, "IDE 4.0 ??" What does that mean ? Forte for Java ? For C++ ? Sun Studio ? It it's Java you're programming in, I can help you on BigInteger issues... ...
Faysal, there is of course the .modPow( BigInteger _exponent, BigInteger _modulus ) method, but that may not help you very much if you want to use a true ...
... I need to clarify that Sun's JVM hasn't used Colin Plumb's library since version 1.2. Since then, BigInteger has been implented in pure Java. If you use...
Alan, you are quite right. Anyway, if I were in Faysal's case, it probably would boil down - and that rather quickly - to option 1, with an eye on option 2. ...
Hello Primehunters ! The new record with 8 simultaneous primes are now: 12'874'261'020'824 * 463# + 88793 12'874'261'020'824 * 463# + 88799 12'874'261'020'824...
... ... + 0, 6, 8, 14, 18, 20, 24, 26 Congratulations on retaking the record! 206 digits is great for 8 primes. http://hjem.get2net.dk/jka/math/simultprime.htm...
Documentation is rather slim regarding the -power and -dickson parameters. As a result, I'm attempting to determine whether these parameters may be used to...
Jan, Alan, Thank you for your support. I wrote a small method using a well known algorithm "Exponentiation by Squaring", but it still take horrible execution...
If it wasn't clear (and it wasn't,) the algorithm I just posted was one to speed up exponentiation. I use it as a wrapper around BigInteger.pow(BigInteger...

There are a lot of consecutive lines without any primes, or primes*primes. For example : 3000000000000000000000000000028 3000000000000000000000000000029 ...
