Steinhaus-Moser Notation

A notation for large numbers defined by Steinhaus (1983, pp. 28-29). In this notation,  denotes ,  denotes " in  triangles," and  denotes " in  squares." A modified version due to Moser eliminates the circle notation, continuing instead with polygons of ever increasing size, so  in a pentagon is  with  squares around it, etc.
