A136010 ?

[Alexander Povolotsky]

 Sorry for bothering everyone ...

But did anyone looked at recently submitted A136010 ?
It looks like a puzzle to me since no verbal definition of the pattern
or mathematical rule of generation is given ...

As far as I could only see is that:

a) The terms starting from the second one are dividable by 9 ...
b) The terms starting from the third one are dividable by 81 ....
