Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

15 (digital sum = 1+5 = 6) is in the list because 15^3=3375 (digital sum = 3+3+7+5 = 18) and 18 = 3*6.
