In this paper, we define the Pell-Padovan p-numbers then we obtain the generating matrix, permanental representation, the Binet formula, the generating function, the exponential representation, the combinatorial representations and the sums of the Pell-Padovan p-numbers. Also, we study the Pell-Padovan p-numbers modulo m. Furthermore, we extend the Pell-Padovan p-sequences to generated groups by two or more elements. Finally, we obtain the lengths of the periods of the Pell-Padovan p-sequences in the unimodular group m(2) the modular group m(2)(+) which is an index 2 subgroup of TT, and the group R-2 which is a commutator subgroup of m(2).
