%N Union of missing numbers in first 10, 100, 1000, 10000, ... digits after the decimal point in expansion of Pi.
%C Analogous to A228988 and A260627.
%H MIT Student Information Processing Board, <a href="https://stuff.mit.edu/afs/sipb/contrib/pi/">One billion (10^9) digits of pi</a>.
%e In the first 10^1 digits of Pi after the decimal (1415926535), the digits 0, 7 and 8 do not appear, so they are members of this sequence.
%e In the first 10^2 digits of Pi after the decimal, the terms 12, 13, 18, ... 90, 91, 96 do not appear, so they are members of this sequence.
