COMMENTS
The sequence seems to be finite but not obviously. Can someone prove this and find the last term?
Conjecture: Sequence is infinite with terms from a(12) onwards alternating between integers with the four digits 4,5,6,9 and integers with the remaining six digits 0,1,2,3,7,8. - William Rex Marshall, Jul 19 2005
