Ignoring the initial zeros issue, it looks to me as if the Cayley
reference suggests this for the number of partitions of floor[3n/2]-1
into up to 3 terms each no more than n (or variants on the same theme),
so explaining why this is close to A001971 </%7Enjas/sequences/A001971>
However that would give 1 for the 1st term, so with no starting zero
A001972 becomes the number of partitions of floor[(3n+1)/2] into up to 3
terms each no more than (n+1) or variants on the same theme.
