Why is 4 the perfect number riddle?

Four is the only number that has the same number of letters in it as the value of that number. The way it works is you take any number, count the number of letters in that number to find the next number that you will use to continue the pattern with until you get back to four.

Are there any self-describing numbers that contain at least one zero?

Because leading zeros are not written down, every autobiographical number contains at least one zero, so that its first digit is nonzero. Considering a hypothetical case where the digits are treated in the opposite order: the units is the count of zeros, the 10s the count of ones, and so on, there are no such self-describing numbers.

Are all self-descriptive numbers multiples of their base?

From the numbers listed in the table, it would seem that all self-descriptive numbers have digit sums equal to their base, and that they’re multiples of that base. The first fact follows trivially from the fact that the digit sum equals the total number of digits, which is equal to the base, from the definition of self-descriptive number.

Is there a self-describing number with 10s?

Considering a hypothetical case where the digits are treated in the opposite order: the units is the count of zeros, the 10s the count of ones, and so on, there are no such self-describing numbers. Attempts to construct one result in an explosive requirement to add more and more digits.
