Input (State) spectrum for a mineral is converted to a series of virtual addresses 
using a generalisation factor (Numcel) of five.

Input (State) spectrum for the same mineral. Note that a change to a single value 
in the spectrum (the first value is changed from 20 to 22) does not change the 
base for calculation but does change two of the virtual addresses. The similarity 
between the two spectra means that memory locations will be shared, in this case 
the third, fourth and fifth locations are in common.
