%N Numbers n having exactly 5 distinct prime factors, the largest of which is greater than or equal to sqrt(n) (i.e., sqrt(n)-rough numbers with exactly 5 distinct prime factors).

%H Robert Israel, <a href="/A115959/b115959.txt">Table of n, a(n) for n = 1..10000</a>

%e 46830 is in the sequence because it has 5 distinct prime factors (2, 3, 5, 7 and 223) and 223 > sqrt(46830).
