Abstract

Let (Pn)n0 (P_n)_{n\ge 0} be the sequence of Perrin numbers defined by ternary relation P0=3 P_0=3 , P1=0 P_1=0 , P2=2 P_2=2 , and Pn+3=Pn+1+Pn P_{n+3}=P_{n+1}+P_n for all n0 n\ge 0 . In this paper, we use Baker's theory for nonzero linear forms in logarithms of algebraic numbers and the reduction procedure involving the theory of continued fractions, to explicitly determine all Perrin numbers that are concatenations of two distinct repeated digit numbers.
