Line 1: − '''Sexy primes''' are pairs of [[prime numbers]] which differ in value by six, for example, 5 and 11 are sexy primes as they are both prime numbers and the difference between then is 6. The term comes from the Latin root word ''sex'', meaning ''six''. Sexy primes are often written algebraically in the form (p, p+6). The largest known pair of sexy primes have 10154 digits.+ + + − Groups of consecutive sexy primes are known as sexy constellations. A sexy triplet contains prime numbers in the form (p, p+6, p+12), for example (17, 23, 29). The numbers making up the largest known sexy triplet contain 5132 digits. Sexy quadruplets are those containing four prime numbers in the form (p, p+6, p+12, p+18), for example (41, 47, 53, 59), the first number of which must end in a 1. The largest known sexy quadruplet is made of primes each having 1002 digits.+ + + + − ==External Links==+ − * [http://mathworld.wolfram.com/SexyPrimes.html Sexy Primes] at Mathworld+ + + + + − [[Category:Number Theory]]+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

A place where nobody dared to go
The love that we came to know
They call it Xanadu
And now
Open your eyes and see
What we have made is real
We are in Xanadu
A million lights are dancing
And there you are
A shooting star
An everlasting world
And you're here with me
Eternally
Xanadu, Xanadu,
(now we are here)
In Xanadu
Xanadu, Xanadu,
(now we are here)
In Xanadu
Xanadu, your neon lights will shine
For you, Xanadu
The love
The echoes of long ago
You needed the world to know
They are in Xanadu
The dream
That came through a million years
That lived on through all the tears
It came to Xanadu
A million lights are dancing
And there you are
A shooting star
An everlasting world
And you're here with me
Eternally
Xanadu, Xanadu,
(now we are here)
In Xanadu
Xanadu, Xanadu,
(now we are here)
In Xanadu
Now that I'm here
Now that you're near in Xanadu
Now that I'm here
Now that you're near in Xanadu
Xanadu...
