I retired in 2006 and bought Mathematica and a stack of math books with the goal to teach myself to become a world-class mathematician. I am on pace to achieve that goal sometime shortly after the next Ice Age.

I consider myself a Mathematical Mutt (no papers) who occasionally ventures off the back porch to play in the yard with the big dogs.

I donate regularly to the The OEIS Foundation.

When I look at the patterns, I can hear the wheels turning. When I look at the math, I find out the hamsters have died.

 Apr 26 revised How to prove non-decreasing sequence?added note about my flawed proof. Apr 26 revised How to prove non-decreasing sequence?added the new expression as mentioned in the coment Apr 26 comment How to prove non-decreasing sequence?@ErickWong, Yes, as it stands, proving that the OP sequence is non-descending, only proves Legendre. I'm reworking to get finer granularity to prove a generalized Bertrand's Postulate and its correlary: Oppermann's Conjecture.
