The number 798 is a “digital daisy-chain”; ie, if you spell out each of its digits as a word, then the last letter of each digit is the first letter of the next. Furthermore, the number 182 is a “looped” digital daisy-chain because, in addition, the last letter of its last digit is the first letter of its first digit.
I have written down a large looped digital daisy-chain (with fewer than a thousand digits!). The total of its digits is itself a digital daisy-chain.
What is that total?
