output terminal nodes. The position of each node is given by the triplet (a, c, h ),
0 £ a £ A1, 0 £ c £ C1, 0 £ h £ H1.
Paths within a cylinder exist only between nodes of adjacent angle values and
never between nodes with the same position around the circumference of the
cylinder, i.e., only from (a, c, h) to (mod

(h)). These edges are often
termed deflection paths because, while they are also used for address resolution,
they are the only links available for deflections. Additional edges are present
between cylinders called ingression paths, which connect nodes of the same height
and of adjacent angle values, i.e., from (a, c, h)
