Based on these options, it is feasible to build 3 3 2 2 2 2 2 2 3
2 2 6,912 tractors without any two being identical; each represents a unique config-
uration of optional features. In this case, it would be possible to use any number of model
designations from 1 to 6,912. For instance, two models could be recognized based on
horsepower, such as:
Model A: 56 hp
Model B: 68 hp

or six models could be recognized, such as:
Model A: 56 hp, four-wheel construction
Model B: 56 hp, three-wheel construction, regular
Model C: 56 hp, three-wheel construction, special
Model D: 68 hp, four-wheel construction
Model E: 68 hp, three-wheel construction, regular
Model F: 68 hp, three-wheel construction, special

The number of models could be raised to 12 by adding, say, axle clearance, to 18 by
adding the fuel option, or to 36 if both were included. In each case, the model code would
tell something—but not everything—about the features of the machine. Depending on
