The first four terms are also called Narcissistic or Armstrong numbers. The first 16 terms are found in the Spencer's book, pages 65 and 101. I calculated the last seven terms.
The sequence contains several infinite subsequences such as 153, 165033, 166500333, 166650003333, ...; 370, 336700, 333667000, 333366670000, ... or 371, 336701, 333667001, 333366670001, ... - Ulrich Schimke (ulrschimke(AT)aol.com), Jun 08, 2001
