True So Far, Base 9

[Graeme McRae]

According to my calculations, there are 1940 elements of True So Far, base 9.  a(1940)=12628, which is 18281 base 9.

The first 100 elements, written in base 10, are: 9, 11, 12, 13, 14, 15, 16, 17, 18, 21, 22, 23, 24, 25, 26, 27, 31, 32, 33, 34, 35, 36, 41, 42, 43, 44, 45, 51, 52, 53, 54, 61, 62, 63, 71, 72, 83, 84, 85, 86, 87, 88, 89, 92, 93, 94, 95, 96, 97, 98, 102, 103, 104, 105, 106, 107, 112, 113, 114, 115, 116, 122, 123, 124, 125, 132, 133, 134, 142, 143, 144, 152, 153, 155, 156, 157, 158, 159, 165, 166, 167, 168, 169, 174, 175, 176, 177, 178, 183, 184, 185, 186, 187, 193, 194, 195, 196, 203, 204, 205.
