To my surprise, there does not seem to be a comprehensive list of indicative characters on the internet. Indicative characters are more often called self explanatory characters in English but in Chinese are called indicative characters (指事字). We may also rightly call them ideograms. Indicative characters are abstract symbols, sometimes derived from pictograms, to express an abstract concept graphically. So for example an arrow, a dot. Most numbers are indicative characters because they are an abstract concept. Some of the indicative characters are inversions of other characters. They are self evident. The dots tend to be used to call attention to a particular aspect of a pictogram. Like pictograms, ideograms generally do not have a phonetic clue as to their pronunciation, though some do. Some ideograms are quite abstract others are referenced to pictograms. They are symbols, abstract expressions of an idea graphically represented.
