Hi MaplePrimes, and all,

Here is a new, to me, set of numbers
defined by ,
the first three numbers are {1,2,3}
and then, 
the next number is the sum of the three 
previous numbers,
so,
{1,2,3,6,11,20, ... }
but can only calculate a finite number of numbers
the, so called, Tribonacci numbers
could start with {0,1,0}

just want to share,
some successful code

The lesser of the twin primes are listed
{3,5,11,17,29,41,59,71}
https://oeis.org/A001359
Prime numbers p such that p+2 is also a prime number

also, the lesser of the cousin primes are listed
{3,7,13,19,37,43,67,79,97}
https://oeis.org/A023200
prime numbers p such that p+4 is also a prime number

good fun

also, my webpage has more details

okay

Hi mapleprimes, and all,

did a little exploration with the Matrix() and ifactor() Maple commands.

have a look
no warnings, and no errors

Hi Maple community, and all,

My intrest in prime numbers continues.

Made a quick example file.

Hi there, distinguished audience,

Let f(n)=n²+n+41.

further, require n to be a positive integer.
Look at the cases when f(n) is a prime number, or a composite number.
Beautiful parabola patterns appear.
see attached

I also look at the case when there is

n²+n+17.
