Apart from the initial term (0), lists all integers whose factorial expansion ends with 1 (i.e. are odd numbers), do not contain a digit zero and each successive digit to the left is at most one greater than the preceding digit.
0, 1, 3, 5, 9, 11, 15, 17, 23, 33, 35, 39, 41, 47, 57, 59, 63, 65, 71, 87, 89, 95, 119, 153
