%N Primorial deflation of A133411(n), where A133411(n) is the smallest highly composite number of the form k*a(n-1) where k is an integer greater than 1.

%C a(n) is the unique integer k such that A108951(k) = A133411(n).

%C Note that this sequence is strictly growing, even though A329902 (whose subsequence this is) is not monotonic.

%C Conjectured to be a subsequence of A330745.
