Note that several terms (e.g. a(10), a(13), a(17)-a(19)) look like the rounding off of a periodic sequence, i.e. yxxxa9xxxa9xxxa9... rounded off to yxxxa9xxxa9xxxb, where b = a+1. Perhaps these can be considered near-cyclic numbers? - _Chai Wah Wu_, Oct 21 2019 %H A326811 Giovanni Resta, <a href="/A326811/b326811.txt">Table of n, a(n) for n = 1..70</a> (first 19 terms from Chai Wah Wu) %Y A326811 Cf.
