### Abstract

This paper develops properties of recurrence sequences defined from circulant matrices obtained from the characteristic polynomial of the Pell-Padovan sequence. The study of these sequences modulo m yields cyclic groups and semigroups from the generating matrices. Finally, we obtain the lengths of the periods of the extended sequences in the extended triangle groups *E*(2, *n*, 2), *E*(2, 2, *n*) and *E*(*n*, 2, 2) for *n* ≥ 3 as applications of the results obtained.
