%N Irregular table: Row n is the list of positive exponents in the canonical prime factorization of A182857(n), sorted in descending order, or 0 if there are no such exponents.
%C Length of row 0 = length of row 1 = 1; for n > 1, length of row n = A011784(n-1).
%C For n > 2, row n = row (n-2) of A012257, reversed.
%e Table begins:
%e 0,
%e 1,
%e 2,
%e 1,1,
%e 2,1,
%e 2,1,1,
%e 3,2,1,1,...
%Y Cf. A181819, A182850.
