  In this paper, bicomplex Pell and bicomplex Pell-Lucas numbers are defined.
Also, negabicomplex Pell and negabicomplex Pell-Lucas numbers are given. Some
algebraic properties of bicomplex Pell and bicomplex Pell-Lucas numbers which
are connected with bicomplex numbers and Pell and Pell-Lucas numbers are
investigated. Furthermore, d'Ocagne's identity, Binet's formula, Cassini's
identity and Catalan's identity for these numbers are given.
