[seqfan] Forbidden digits =2016

[Eric Angelini]

Hello SeqFans,

here is an attempt to build a seq were :
-- a(n) and a(n+1) do not contain 2, 0, 1 or 6
-- the sum a(n)+a(n+1) does not contain 2, 0, 1 or 6
-- the product a(n)*a(n+1) does not contain 2, 0, 1 or 6

   S  =  5,    79,    455,   7439, ...
Sum:        84    534    7894
Prod:      395   35945  3384745

I don't know if this is the lexicographically first
such seq -- but it seems to work...

Best wishes for the next year to you all -- and many
thanks to the Seqfans who have helped, corrected and
published some of my silly ideas of 2015!
