[seqfan] Sharing no digit business

[Eric Angelini]

Hello SeqFans,
I'm still in the "Sharing no digit" business... Could
someone please check this seq:

"a(n) shares no digit with the a(n)th term of the sequence"

a(1)=2 -- and to extend the seq, always add the smallest
          integer not used so far.

S = 2,1,4,3,6,5,8,7,10,9,12,30,14,20,16,22,18,23,21,31,33,34,...

(a nightmare to do by hand)

Best,
E.

(terms *not* in S are also of interest: 11,13,15,17,19,...)
