%N Values of n for which A095777(n) is 15 (those terms which are expressible in decimal digits for bases 2 through 16, but not for base 17).
%e a(5)=99 because 99 when expressed in successive bases starting at 2 will produce its first nondecimal digit at base 17. Like so: 1100011, 10200, 1203, 344, 243, 201, 143, 120, 99, 90, 83, 78, 71, 69, 63. In base 17, 99 is 5E.
%p S := []; for n from 1 to 5000 do; if 1>0 then; ct := 0; ok := true; b := 2; if (n>9) then; while ok=true do; L := convert(n, base, b); for e in L while ok=true do; if (e > 9) then ok:=false; fi; od; if ok=true then; ct := ct + 1; b := b + 1; fi; od; fi; if ct=15 then S := [op(S), n]; fi; fi; od; S;
%Y Cf. A095777.
