%N Numbers whose cyclic permutations are pairwise coprime.
%C No term, except 10, contains a '0' digit.
%C No term contains two even digits.
%C No term > 9 is a multiple of 3.
%C No term contains two '5' digits.
%C This sequence contains A287198.
%C This sequence does not contain any term > 9 of A084433.
%C In the scatterplot of the first 10000 terms:
%C  the jump from a(7128) = 99998 to a(7129) = 111112 is due to the fact that there is no term > 10 starting with "10",
%C  the dotted lines, for example between a(2545) = 21131 and a(2772) = 29999, are due to the fact that there is no term starting with two even digits,
%C  these features can be seen at different scales (see scatterplots in Links section).

%e The cyclic permutations of 5992 are:
%e  5992 = 2^3 * 7 * 107
%e  9925 = 5^2 * 397
%e  9259 = 47 * 197
%e  2599 = 23 * 113.
%e These values are pairwise coprime, hence 5992 appear in the sequence.
%e The cyclic permutations of 5776 are:
%e  5776 = 2^4 * 19^2,
%e  7765 = 5 * 1553,
%e  7657 = 13 * 19 * 31,
%e  6577 = 6577.
%e gcd(5776, 7657) = 19, hence 5776 does not appear in the sequence.
