Simplicity
The number of operations needed to effect a Geometric Construction as determined in Geometrography. If thenumber of operations of the five Geometrographic types are denoted 
, 
, 
, 
, and
, respectively, then the simplicity is 
and the symbol 
. It isapparently an unsolved problem to determine if a given Geometric Construction is of smallest possible simplicity.
