Mersenne primes and perfect numbers are two deeply interlinked types of natural numbers in number theory.Mersenne primes, named after the friar Marin Mersenne, are prime numbers that can be expressed as 2 p 1 for some positive integer p.For example, 3 is a Mersenne prime as it is a prime number and is expressible as 2 2 1. 85037 85049 85061 85081 85087 85091 85093 85103 85109 85121 There is also a Prime Number Tester which will tell you whether or not a given number is 11549 11551 11579 11587 11593 11597 11617 11621 11633 11657 The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. 48311 48313 48337 48341 48353 48371 48383 48397 48407 48409 Here are the where x=y + 2. 2, 3, 5, 7, 11, 101, 131, 151, 181, 191, 313, 353, 373, 383, 727, 757, 787, 797, 919, 929, 10301, 10501, 10601, 11311, 11411, 12421, 12721, 12821, 13331, 13831, 13931, 14341, 14741 (OEIS:A002385). 4073 4079 4091 4093 4099 4111 4127 4129 4133 4139 6. 77557 77563 77569 77573 77587 77591 77611 77617 77621 77641 Lists of the first primes. 27581 27583 27611 27617 27631 27647 27653 27673 27689 27691 The name "emirp" is obtained by reversing the word "prime".
