COMMENTS

Recall that A114994 can be regarded as a table with row lengths A000041(n).
Likewise, a(n) has row lengths 0,1,1,3,3,7,8,14,18,28,35,53,67,... which appears to coincide with sequence A117989.
The row lengths also match 1 2 3 5 7 11 15 22 ... minus 1 1 2 2 4 4 7 8 ...  Alford Arnold, Mar 30 2010
