 A290386 Increasing sequence a(n)>a(n-1) where a(n)=smallest integer not yet in the sequence with no digits shared with the previous term a(n-1), no repeated digits, and no 0-digit allowed. 2
 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 34, 51, 62, 71, 82, 91, 234, 516, 723, 814, 923, 1456, 2378, 4156, 7238, 9145, 23678 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS The fact that the sequence is increasing makes it finite. LINKS EXAMPLE 12 follows 9 since 10 has the digit 0 and 11 has a repeated digit. 34 follows 12 since any number in between either shares a digit with 12, has a 0 (30), or a repeated digit (33).
