A095781 Values of n for which A095777(n) is 12 (those terms which are expressible in decimal digits for bases 2 through 13, but not for base 14). 0

LINKS

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

EXAMPLE

a(5)=40 because 40 when expressed in successive bases starting at 2 will produce its first non-decimal digit at base 14. Like so: 101000, 1111, 220, 130, 104, 55, 50, 44, 40, 37, 34, 31. In base 14, 40 is 2C.

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=12 then S := [op(S), n]; fi; fi; od; S;
