[seqfan] Partitions of n into squared divisors

[Richard Mathar]

Is the number of partitions of n, such that each part is a square of a 
divisor of n, in the OEIS? This is related to A018818, which demands that
each part is a divisor of n, and is related to the question in how many ways
a group of order n allows decomposition into irreducible subgroups where the
characters need to be divisors of the group order. Maybe I am overlooking
something.
This sequence ought start at n=1 (ie, with offset 1) as

      1, 1, 1, 2, 1, 2, 1, 3, 2, 3, 1, 5, 1, 4, 2, 6, 1, 9, 1, 8, 3, 6, 1
and represent the following partitions n [terms of partition] for small n:

                                     1, [1]

                                   2, [1, 1]

                                  3, [1, 1, 1]
