Example

The ternary representation of 84 is 10010, for which c(0)=3 > c(1)=2 > c(2)=0.

Mathematica

Select[Range[1000], DigitCount[#, 3, 0] > DigitCount[#, 3, 1] > DigitCount[#, 3, 2] &]

Prog

(MATLAB) nmax = 1000; n = 1:nmax; for k = 1:nmax, c = arrayfun(@(m) sum(dec2base(k, 3)-'0'==m), 0:2); tf(k) = c(1)>c(2) && c(2)>c(3); end, a = n(tf); % Chris R. Rehmann, Oct 24 2025
