COMMENT

Complement of A119247.
For terms u: all digital permutations of u form terms; u*10 and all insertions of 0 are terms; if v is another term, then the concatenations uv, vu are also terms, as well as all insertions of v in u; these properties allow to construct all terms beginning with {d:1<=d<=9}. - Reinhard Zumkeller (reinhard.zumkeller(AT)gmail.com), May 19 2006
