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.

I see pyramid on left, pyramid hole on right. I don't see a triangle.

+1, another fine answer. I'll play with it for a few days before I accept anything.

A003814 == (j = Table[n, {n, 1, 10}]) works!

I tried it and it's getting closer. It finds the OEIS page. I'm still playing with it.

Assignment (=) doesn't work. This does work A003814 == Table[n, {n, 1, 10}] except the hyperlink keeps the entire string so doesn't find anything. So the StringJoin should truncate at 7 characters.

+1, looks promising.
