%N A188454 Numbers n whose decimal digits are distinct and no digit divides n.
%C A188454 These may not contain 1 or have a 2 or 5 as the last digit. They include prime numbers not containing the digit 1 and composites with a smallest prime factor > 10 and obeying the other constraints (e.g. the largest case is 987654203 = 31*31859813).
%C A188454 The first even case is 34. The first consecutive pair is {37, 38}. {56,57,58,59} is a consecutive quadruple which is the maximal size for such a subset.
%C A188454 There are 202623 terms in this sequence. - _Nathaniel Johnston_, May 19 2011
