Prime – a natural number great than 1 that
has no positive divisors other than 1 and
itself.
Quadruplet – a grouping of 4
a set of four prime numbers in the form
{p, p+2, p+6, p+8}
A representative of the closest possible
grouping of four primes larger than 3
The smallest prime quadruplet is {5, 7, 11, 13}
followed by {11, 13, 17, 19}
All prime quadruplets take the form
{30n+11, 30n+13, 30n+17, 30n+19} with the
exception of the first prime quadruplet.
The first few values of n which give prime
quadruples are n=0, 3, 6, 27, 49, 62, 69, …
The width of a prime quadruplet is 8.
Three consecutive odds cannot be a part of a
prime quadruplet since can interval of seven
or less cannot contain more than three odd
numbers unless one of them is a multiple of
three.
Prime quadruplets that take the form
{30n+11, 30n+13, 30n+17, 30n+19} are called
prime decades.
The terms in the prime decade all start with
the same number.
In 1982 a 45-digit prime quadruplet was
discovered by M. A. Penk.
In 1998, the prime quadruplet with more than
1000 digits was found at the end of an 8 day
search on a computer that used 1400 MHz of
Pentium computer power.
There are also Prime Quintuplets keeping the
same form {p, p+2, p+6, p+8} as the prime
quadruplets with the addition of p-4 or p+12
and Prime Sextuplets which is when both p-4
and p+12 are prime with {p, p+2, p+6, p+8}
Are there infinitely many prime quadruplets?
