It is worth emphasising that numbers like 1, 1/3 = 0.13 and 7/9 = 0.213 are in the Cantor set, as they have ternary numerals consisting entirely of 0s and 2s: 1 = 0.2222...3, 1/3 = 0.022222...3 and 7/9 = 0.2022222...3.
To pomeni, da vsako trojiška decimalko, oblike 0,1xxxxxx, odstranimo iz množice, razen tiste, kjer je vsak "x" enak 0 ali vsak "x" 2 - to sta krajni točki.
