A095780 Values of n for which A095777(n) is 11 (those terms which are expressible in decimal digits for bases 2 through 12, but not for base 13).

Table of n, a(n) for n=1..56.

Example

a(5)=37 because 37 when expressed in successive bases starting at 2 will produce its first non-decimal digit at base 13. Like so: 100101, 1101, 211, 221, 101, 52, 45, 41, 37, 34, 31. In base 13, 37 is 2B.

Maple

S := []; for n from 1 to 1000 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=11 then S := [op(S), n]; fi; fi; od; S;
