theorem-h-orientation / cage-laws

Law C, law \(P^k\), Lemmas 1 to 3 (the cage laws)

The local linear laws the frozen condition imposes on the types round each hole, with the 1,200 possible patterns of one cage.

The linear identities between the type indicators of the vertices of a cage that (T2) implies, including the law \(P^k\) relating the rods and bridgeheads of a hole, and Lemma 3, the enumeration of the 1,200 patterns of one cage.
