Mathematician working in modelling/simulation at an econometric consulting firm in Washington, DC. Interests are: combinatorics, experimental mathematics, mathematical databases . I have contributed two sequences to Sloan's database:

A293462: Let $A_n$ be a square $n\times n$ matrix with entries $a_{ij}=1$ if $i+j$ is a perfect power and $a_{ij}=0$ otherwise. Then A293462 counts the $1$'s in $A_n.$ It has been conjectured this sequence increases monotonically.


A292918: Let $A_n$ be a square $n\times n$ matrix with entries $a_{ij}=1$ if $i+j$ is a prime number and $a_{ij}=0$ otherwise. Then A292918 counts the $1$'s in $A_n.$

Paul Halmos - "Mathematics is not a deductive science—that's a cliché. When you try to prove a theorem, you don't just list the hypotheses, and then start to reason. What you do is trial and error, experimentation, guesswork. You want to find out what the facts are, and what you do is in that respect similar to what a laboratory technician does
