2178 and All That

For integers g ≥ 3, k ≥ 2, call a number N a (g, k)-reverse multiple if the reversal of N in base g is equal to k times N . The numbers 1089 and 2178 are the two smallest (10, k)reverse multiples, their reversals being 9801 = 9 · 1089 and 8712 = 4 · 2178. In 1992, A. L. Young introduced certain trees in order to study the problem of finding all (g, k)-reverse multiples. By using modified versio...
