7 <str<strong>on</strong>g>Number</str<strong>on</strong>g> Rewrite<br />
Though this system is limited to the integers, Kauman has dened another<br />
boundary as the opposite <str<strong>on</strong>g>of</str<strong>on</strong>g> the magnitude boundary, such that () = : = : A:<br />
The string rewrite rules for this system are quite extensive due to the many permutati<strong>on</strong>s<br />
<str<strong>on</strong>g>of</str<strong>on</strong>g> the characters and are not included here.<br />
Alternatively, the extended Kauman numbers can be dened spatially with three<br />
rules. The deniti<strong>on</strong> below uses his delimiter form <str<strong>on</strong>g>of</str<strong>on</strong>g> the inverse rather than the<br />
overbar form shown above [24].<br />
Double AA = : <br />
Inverse A[A] =<br />

Half () = : = : A<br />
Kauman numbers represent the integers and the system computes basic arithmetic<br />
operati<strong>on</strong>s except divisi<strong>on</strong> and powers. Additi<strong>on</strong> by collecti<strong>on</strong> is immediate, as<br />
is multiplicati<strong>on</strong> by substituti<strong>on</strong>. Reducti<strong>on</strong> is d<strong>on</strong>e locally by string rewrite rules.<br />
2.3 Bricken <str<strong>on</strong>g>Number</str<strong>on</strong>g>s<br />
Kauman's work was given a dierent twist by William Bricken, who interpreted his<br />
basic forms as networks [5]. The network form provides singular references and a clear<br />
representati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the structures being manipulated. Of particular benet, singular<br />
reference allows multiplicati<strong>on</strong> by stacking, providing an algebraic form. Bricken<br />
numbers are summarized in Table 2.3.<br />
Bricken numbers are networks whose value is determined by their c<strong>on</strong>nectivity.<br />
The network includes a c<strong>on</strong>text and ground, shown as lines above and below the
