  The aim of this paper is twofold. The first one is to find several relations
between the type 2 higher-order degenerate Euler polynomials and the type 2
higher-order Changhee polynomials in connection with the degenerate stirling
numbers of both kinds and Jindalrae-stirling numbers of both kinds. The second
one is to introduce the discrete harmonic numbers and some related polynomials
and numbers, and to derive their explicit expressions and an identity.
