The following diagram shows an example of the canonical structure ''(<u>O</u>'', ϵ'')'', together with corresponding Python code.

The structure contains 6 [[#Primary_objectsPrimary objects|primary objects]]:

2 [[#Helix|helix]] classes

(the [[#Inheritance_rootInheritance root|inheritance root]] ''<u>r</u>'' and the [[#Instance_rootInstance root|instance root]] / metaclass root ''<u>c</u>''),

3 other [[#Classes|classes]] (<code>M</code>, <code>A</code> and <code>B</code>),

and 1 [[#Terminal_objectsTerminal objects|terminal object]] (<code>b</code>).

Right-directed arrows (in gray) show the eigenclass map,

up-directed arrows (in green) show the child-parent relation of [[#Inheritance|inheritance]].

The <span style="{{color:|green">|''∫''</span>}}-shaped arrows are the [[#Twist_linksTwist links|twist links]].

[[#Eigenclasses|Eigenclasses]] are shown as unnamed nodes in gray. Each eigenclass chain is infinite &ndash; the diagram displays just an initial part, without descendants of the fourth eigenclass of ''<u>r</u>''.
