Less than a year after the 43rd Mersenne prime was reported (*MathWorld*December 25, 2005), the Great Internet Mersenne Prime Search (GIMPS) project has discovered the 44th known Mersenne prime. Mersenne numbers are numbers of the form *Mn* = 2*n* – 1, giving the first few as 1, 3, 7, 15, 31, 63, 127, …. Interestingly, the definition of these numbers therefore means that the *n*th Mersenne number is simply a string of *n* 1s when represented in binary. For example, *M*7 = 272 is a Mersenne number. Mersenne primes are Mersenne numbers that are also prime, i.e., have no factors other than 1 and themselves. So, since the number 127 is prime and is a Mersenne number, it is a Mersenne prime. – 1 = 127 = 1111111]The Vedic Math Forum India celebrates this fact and applauds the same.
