• Prime divisors of palindromes 

    Banks, William David, 1964-; Shparlinski, Igor E. (Springer Verlag, 2005)
    In this paper, we study some divisibility properties of palindromic numbers in a fixed base g ≥ 2. In particular, if PL denotes the set of palindromes with precisely L digits, we show that for any sufficiently large value ...
