Steinhaus-Moser Notation

A Notation for Large Numbers defined by Steinhaus (1983, pp. 28-29). In this notation, denotes $n^n$, denotes ``$n$ in $n$ Triangles,'' and denotes ``$n$ in $n$ Squares.'' A modified version due to Moser eliminates the circle notation, continuing instead with Polygons of ever increasing size, so $n$ in a Pentagon is $n$ with $n$ Squares around it, etc.
