%N Sevendigit terms in A023086 Numbers n such that n and 2*n are anagrams.
%C All 288 terms have only two sets of digits: {{0,1,2,4,5,7,8},{1,2,4,5,7,8,9}} with exactly equal numbers of both sets = 144.
%C There are six 7d numbers n such that n, 2*n and 4*n are anagrams, that is intersection of 7d subsequences in A023086 and A023088: 1294857, 1428507, 1428570, 1428705, 1429857, 1492857.
%C These are all "norep" numbers, i.e., numbers with any repetitive digit are not permitted. [From Harvey P. Dale, Oct 30 2011]
