Comments

A pair of numbers x and y are called amicable digital if, 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.

First differs from A264958 (another version) at a(9).
