Things to #nerd out with on a sick day:

I started looking at #semiprime numbers whose factors were reversals of each other. Like 2701 = 37 x 73. Fun enough right?

Just wait!!

721243 is #prime. Reversed it’s 342127 which is a semiprime whose factors are… 359 x 953.

Mind. Blown. :apartyblobcat:

Ok not really but this is fun shit I NEVER have time to #geek around with 🤓

#OEIS A275600, A265438

1382 can be written with only 0's, 1's, and 2's from base 2 to base 6.
It is also a palindrome base 5; 21012.

There are 120 permutations of the digits 1,2,3,4,5. All of them are of the form 9x+6. 1371 is the first 'x' in this sequence.
