As of 7/27/2024, this blog had its 30,000th view. That is certainly not Tik Tok influencer volume, but I'm happy that thousands of visitors have had the opportunity to learn a few new things.

I did a preliminary search for 30,000 to see if there are any interesting facts. Wikipedia has listings for many numbers and it led me to its page where it lists interesting numbers in ranges. For the range 30,000 to 30,999, it listed the following with a few referencing sequences from On-Line Encyclopedia of Integer Sequences (OEIS) - a favorite site of this blog.

• 30029 = primorial prime
• 30030 = primorial^[1]
• 30031 = smallest composite number which is one more than a primorial
• 30203 = safe prime
• 30240 = harmonic divisor number^[2]
• 30323 = Sophie Germain prime and safe prime
• 30420 = pentagonal pyramidal number^[3]
• 30537 = Riordan number
• 30694 = open meandric number
• 30941 = first base 13 repunit prime
