welcome in new person

Have a nice day

:rant: Do it again and you will be put in the sin bin for a while.

All possible
Have a nice day

In my world, conjecture is like probably true

Sounds good

appreciate your efforts

Primes as not a possible numerical anagram ... interesting
Here is some simple minded Maple code. The hardest part was counting all the 2s.

> for a from 2 by 2 to 100 do
if isprime(222222222222222219+a) then print(222222222222222219+a, "is prime") end if end do;

222222222222222221, "is prime"
222222222222222281, "is prime"
A pair of p18. (18 digit prime numbers)

Have a nice day.
I put another code snippet at my web-page - [URL="mattanderson.fun"]mattanderson.fun[/URL]
Try to find under "more files" 'prime but not anagram.txt'

okay, after some manual searching, I found a not-anagram cosisting of 63 twos and one 7.

Anyone else can find bigger not-anagram primes using a similar technique.

It is clear to me that anyone with the right software, and a little effort, one can find bigger than a 95 digit ,
not an anagram prime number.
Maple is a fine tool.
Have a nice day.




Wishing you all the best.

Every input is valuable. But all of what you wrote are [B]not [/B]anagrams.

I found a thing
 

Since I have a handy dandy tool that can deal with large integers (Maple Software)
I have found a 121 digit prime.

> temp := 2222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222221;

if isprime(temp) then print(temp, " is prime") end if;

# good fun :--)

And to be sure, an anagram deals with the English language.
This is a fast and loose post.
Cheers !!!

So is [URL="https://www.youtube.com/watch?v=hRrBnI5L0u8"]this.[/URL]

Imagine a young child with a C64, and a subscription to [URL="https://www.scientificamerican.com/article/mandelbrot-set/"]Scientific American[/URL].

While that child worked at a sawmill to pay for his later education.

And coded... Day in. Day out...

And, stayed away many nights wondering if there really was a dog...
