# Structure in a Set. Groups

Chapter

## Abstract

The distinction was drawn in Chapter 1 between the set {*l*, *r*, *n*} of *positions* of the rotary unit of the steering-gear, and the set {*α*, *β*, *γ*} of possible *movement-decisions*. The latter was seen to have the property that any pair of elements can be combined, and that every such combination is itself indistinguishable from some single member of the set. The table which exhibits such combinations was shown in full in the solution of Ex. 1.1 and is repeated here.
