 A067566 Smallest k such that k=n*A001414(k) (or 0 if no such k exists), where A001414(k) is the integer log of k, i.e. Sum p_i*e_i if the prime factorization of k is Product p_i^e_i. 0

 OFFSET 1,1 LINKS EXAMPLE a(3)=27 since 27=3^3 and 27=3*(3*3), but not 30 despite 30=2^1*3^1*5^1 and 30=3*(2*1+3*1+5*1) because 27 is less than 30. CROSSREFS Cf. A001414, A056240.
