Antonio Hernandez Maquivar

Mathematician working in modelling/simulation at an econometric consulting firm in Washington, DC. Interests are combinatorics, number theory and games (finite or otherwise). I have contributed the following 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 $A_n.$
