  In this paper, the Pell-Narayana sequence modulo m is studied. The paper
outlines the definition of Pell-Narayana numbers and some of their
combinatorial links with Eulerian, Catalan and Delannoy numbers and other
special functions. From the definition, the Pell-Narayana orbit of a
2-generator group for a generating pair $(x, y) \in G$ is defined, so that the
lengths of the period of the Pell-Narayana orbit can be examined. These yield
in turn the Pell-Narayana lengths of the polyhedral group and the binary
polyhedral group for the generating pair $(x,y)$ and associated properties.
Also, the period of the Pell-Narayana orbit of the groups $Q_8$, $Q_8
\times\mathbb{Z}_{2m} $ and $Q_8 \times_\phi \mathbb{Z}_{2m} $ for $m \geq 3$
were obtained.
