The correct formula is a(n) = A000142(n) / A076928(n).

It seems that one of the formulas given in A104350,
a(n)=A076928(n)*A000142(n),
is wrong, and only correct for the first 3 terms. The Maple functions to
compare the sequences are below. With a little bit of effort one could
probably figure out which product of which factors is actually 
missing...
