I`m really into sports databases - especially baseball and futbol (Soccer in the U.S.). I started looking at math in my late 30`s ! I consider myself an ok(-ish) amateur mathematician with more curiosity than my skills can manage. I am also a National Team Coach for the United States Olympic & Paralympic Committee (USOPC) and so Team USA. I have a few sequences in Sloan`s database: : Let $A_n$ be a square $ntimes n$ 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. : Let $A_n$ be a square $ntimes n$ 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 $A_n.$ and ; which are the numerators and denominators of the partial product representation of $frac{pi}{4}.$ In particular $prodlimits_{pleq n}frac{1}{1-(-1)^{(p-1)/2}p^{-1}}=frac{A323551}{A323552}$ ©
