&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;We use the following (ASCII) notation for hyperoperations:&lt;br /&gt;
&lt;br /&gt;
b [1] x = b + x&lt;br /&gt;
&lt;br /&gt;
b [2] x = b*x&lt;br /&gt;
&lt;br /&gt;
b [3] x = b^x&lt;br /&gt;
&lt;br /&gt;
For the left- and right-inverse we write:&lt;br /&gt;
&lt;br /&gt;
b [r] x = y (r is called the [[rank]] of the operation)&lt;br /&gt;
&lt;br /&gt;
y /[r] x = b&lt;br /&gt;
&lt;br /&gt;
b [r]\ y = x&lt;br /&gt;
&lt;br /&gt;
This is adapted from the [[wikipedia:quasigroup|quasigroup]] naming.&lt;br /&gt;
