About

I am a high school math teacher. I am a regular contributor to Sloane's OEIS. I study math in most of my leisure time (about 40 hours per week). My Wiki page on OEIS reveals more information about my current abilities and math interests. I never ever down-vote for any reason what-so- ever ever.
