A095779 Values of n for which A095777(n) is 10 (those terms which are expressible in decimal digits for bases 2 through 11, but not for base 12).

11, 22, 23, 34, 35, 46, 47, 58, 59, 70, 71, 82, 83, 94, 95, 106, 107, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 143, 154, 155, 166, 167, 178, 179, 190, 191, 202, 203, 214, 215, 226, 227, 250, 251, 262

Examples

			a(5)=35 because 35 when expressed in successive bases starting at 2 will produce its first non-decimal digit at base 12. Like so: 100011, 1022, 203, 120, 55, 50, 43, 38, 35, 32. In base 12, 35 is 2B.
