  We present an exhaustive classification of the 2644 causally complete spaces
of input histories on 3 events with binary inputs, together with the algorithm
used to find them. This paper forms the supplementary material for a trilogy of
works: spaces of input histories, our dynamical generalisation of causal
orders, are introduced in "The Combinatorics of Causality"; the sheaf-theoretic
treatment of causal distributions is detailed in "The Topology of Causality";
the polytopes formed by the associated empirical models are studied in "The
Geometry of Causality".
