We define a triangular array closely related to Stern’s diatomic array and show that for a fixed integer r ≥ 1, the sum ur(n) of the rth powers of the entries in row n satisfy a linear recurrence with ...

Laxton introduced a group structure on the set of equivalence classes of linear recurrence sequences of degree 2. This result yields much information on the divisibilities of such sequences. In this ...
