Appears in sequences

• Let n = d_1 d_2 ... d_k in base 10 and f(n) = Sum_{i=1..k} d_i^k; sequence gives numbers n such that n != f(n) but n = f(f(n)).at n=11A101335
• Amicable digital pairs: The larger number of a pair (x,y) with x <> y such that, in decimal notation and with an appropriate number of leading zeros prepended, x=(x_m...x_1x_0)_{10}, y=(y_m...y_1y_0)_{10}, x = y_m^m + ... + y_1^m + y_0^m, and y = x_m^m + ... + x_1^m + x_0^m.at n=9A262092
• Amicable digital pairs: A262091 and A262092 interleaved.at n=19A262615
• Amicable digital numbers.at n=20A264951
• Amicable digital pair: the pairs from A262615 ordered by their smallest member.at n=19A264958
