A095782 Values of n for which A095777(n) is 13 (those terms which are expressible in decimal digits for bases 2 through 14, but not for base 15).

14, 28, 29, 42, 44, 56, 57, 72, 73, 74, 85, 86, 100, 104, 196, 198, 199, 200, 201, 204, 210, 211, 212, 213, 216, 217, 224, 253, 254, 295, 392, 393, 396, 397, 398, 399, 434, 435, 436, 437, 438, 448, 449, 462, 463, 464, 507, 508, 509, 520, 521, 522, 523, 524

Examples

			a(5)=44 because 44 when expressed in successive bases starting at 2 will produce its first non-decimal digit at base 15. Like so: 101100, 1122, 230, 134, 112, 62, 54, 48, 44, 40, 38, 35, 32. In base 15, 44 is 2E.
