I posted a reply which reads, "Not a prime number." I was aiming for the type of disconnected side comments 45 makes when he is rambling. The mop "part number" removal which your original post experienced is amusing. Upthread, there was a comment that all the digits are primes or powers of primes. I do not think that is significant, since the number 6 is the only digit which exists and does not fit that description. It is fun to kick around number trivia based upon lessons which we all learned so long ago in math class.

Hi, Torchlight. I have been meaning to reply to you, but my post keeps winding up in the wrong spot. John1956PA Aug 2023 #19

An interesting number. All of the digits except 9 are Fibonacci numbers and are... NNadir Aug 2023 #6
