 OFFSET 0,1 COMMENTS Probably, the last nonzero term is a(401) = 2^71*3^45*5^9*7^4. - Giovanni Resta, Jul 14 2015 LINKS Vincenzo Librandi, Table of n, a(n) for n = 0..1000 FORMULA a(n) = A007954(A000032(n)). - Michel Marcus, Jul 05 2015 EXAMPLE 9349 is the 19th Lucas number; its digit product is 972, therefore a(19) = 972. 15127 is the 20th Lucas number; its digit product is 70, therefore a(20) = 70.
