Note:
In Fig's. -6(a), -6(b), -6(e)
the "odd" stack is shown as the vertical stack.
The structure contains left- & right-handed nodes,
like those shown in Fig's. -6(c) & -6(d) respectively.
They are interdistributed among each other in a manner
as shown schematically in Fig. -6(e).
These left- & right-handed nodes are
interdistributed among each other
in such a fashion that
single-layer strata of only left-handed nodes
alternate with
single-layer strata of only right-handed nodes.
These strata are coincident - in a one-with-one fashion -
with the fabrics of the odd stack.
