 Hints (Greetings from The On-Line Encyclopedia of Integer Sequences!)
 A101246 When this sequence is interleaved with its first differences and the resulting sequence is divided into blocks of 10 digits, each block contains 10 distinct digits. Each term is chosen to be the smallest that satisfies this property. 1

 OFFSET 1,2 COMMENTS Is this sequence infinite? LINKS Table of n, a(n) for n=1..33. EXAMPLE 1.3.7...60|5.607...14|46..1529..|..8531 .2.4.598..|.2...839..|..83....70|02.... Block 1---|Block 2---|Block 3---|etc. After placing a(10) = 9234, digits 41 through 49 are 178569234, so digit 50 is 0 and this is the difference a(11)-a(10); therefore a(11) = 9234.
