                     3    5
                  7    9    11
              13   15   17    19
           21   23   25    27    29


I think that's how it looks.

1 & Primal Pyramid.

I'm unfamiliar with primal pyramids, but I'm really sure that 9, 15, 21 and 25 aren't primes.

It's a pyramid of odds that has some kind of theory with it.  We looked at it for about 15 minutes back in my number theory class.  There's a set of equations that go with it, but I really don't remember anything other than it's called a primal pyramid :\

Yeah, there was a pyramid of odds on some problem in a math meet today. Why do you ask? I first thought that you may have been at that math meet, but then I saw that you live in Wyoming ;\

It was a question on a quiz in calculus (don't ask why he gave it to us because I have no idea).
