%N 7-rough abundant numbers.
%C Each term has at least A001276(4) = 15 distinct prime factors and A108227(4) = 18 prime factors counted with multiplicity. - _Jianing Song_, Apr 13 2021
%C The smallest term with exactly 15 distinct prime factors is a(830) = 465709156638373299218537971 = 7^3 * 11^2 * 13^2 * 17^2 * 19 * 23 * ... * 61. - _Jianing Song_, Apr 14 2021

%e k = 20169691981106018776756331 is in the sequence as its smallest prime factor is at least 7 and it is abundant as sigma(k) > 2*k.
%o (PARI) is(n) = gcd(n, 30) == 1 && sigma(n) > 2*n
