%N Numbers which can be expressed with fewer 1s using +, -, and * than with + and *.
%C Numbers n such that A005245(n) > A091333(n). Is it true that a(n) ~ n?

%e 23 = 2*3*4 - 1 = 3*(2*3 + 1) + 2 can be written with 10 1s using subtraction but requires 11 without, hence 23 is a member. Here the digits 2, 3, and 4 are used for clarity, but could be expanded to (1+1), (1+1+1), etc.
%Y Cf. A091333, A005520, A005245, A173419, A255641.
