What is the maximum number of times the symbols I X C M can be repeated in a number at any given time?

In Roman numerals, the symbols I, X, C, and M can be repeated up to three times in a row to represent numbers. For example, III represents 3, XXX represents 30, CCC represents 300, and MMM represents 3000. Any repetition beyond three times would break the standard Roman numeral rules and would not be considered a valid representation of a number.
