• 5th-order digital invariants: the sum of the 5th powers of the digits of n equals some number k and the sum of the 5th powers of the digits of k equals n.at n=6A072896
• Numbers k such that the k-th triangular number contains each of the 10 decimal digits exactly once.at n=30A115939
• Recurring digital invariants of order 5.at n=8A218246
• Amicable digital pairs: The smaller 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=4A262091
