%N Energetic numbers, allowing zero as an exponent.
%C Numbers that can be broken into two or more substrings and expressed as a sum of (possibly different) nonnegative powers of those substrings.
%C 254 = 2^7 + 5^3 + 4^0 is the first element requiring a zero exponent.
%e 142 = 14^1 + 2^7, 8833 = 88^2 + 33^2.
%Y Cf. A055480.
