At G4G13 with Richard Guy

I was very happy to hang out with my oldest coauthor, Richard Guy, at the Gathering for Gardner conference in Atlanta in April 2018. By the way, Richard Guy is 101 years old.

    Hello, I am a brazilian software developer interested in Math.

    I am using your site to study about interesting number properties.

    My goal is to implement some computer programming libraries about them.

    Keep the good work.
