 A175427 Starting values which reach a single-digit number after a finite number of iterations of the map x->A175429(x). 8
 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 27, 28, 29, 30, 31, 32, 33, 34, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,3 COMMENTS Arguments m such that A175424(m) >= 0. Also arguments m such that A175419(m) >= 0. Complement of A175426. LINKS EXAMPLE 27 is in the sequence because a single-digit number is reached in 3 iterations: 7^2 = 49, 9^4 = 6561, ((1^6)^5)^6 = 1, so A175424(27) = 3. CROSSREFS See A175419 - A175426.
