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).

12, 24, 25, 36, 37, 38, 49, 50, 51, 62, 63, 64, 75, 77, 88, 89, 90, 101, 102, 103, 144, 145, 146, 147, 148, 149, 150, 151, 152, 156, 157, 158, 159, 160, 161, 162, 163, 165, 168, 180, 181, 192, 193, 194, 205, 206, 207, 218, 220, 244, 245, 246, 257, 258, 259, 297

Examples

			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.
