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.

comment For $k>3$ does there exist an odd prime $q_k$ such that $p_k=2^kq_k+1$ is prime and $p_k$ divides $a_k=\dfrac{3^{2^{k-1}}+1}{2}$?
You can finish up by accepting one of the answers.

@jgon, the pattern is very rigid and I would like to know if one could claim that this pattern always exists, i.e., is immutable. I have two more squares that behave in a similar manner. This is an area of math with which I'm not familiar.

@Mr.Wizard, I wondered that too. I usually use FullSimplify after the Reduce to use the code elsewhere.

+1, FullSimplify is just the ticket!

@ChipHurst, I didn't know the default domain, however using Reals also doesn't work.

@GFauxPas, Ordered refers to ascending order of the values, i.e., like an ordered list.
