[seqfan] Re: Jablan/Sazdanovic formula

[Robert G. Wilson v]

Et al,

	Even using Jean-Paul's correction, I am not able to reproduce the
sequence.

Mmca: f[n_] := Sum[(-1)^k*Binomial[n, k]*Floor[2 n/(2 n - k)]*2^k*(2 n -
k)!/(2^n*n!), {k, 0, n}]; Array[f, 6, 2]
They returns: {2, 4, 37, 328, 3656, 47843}

Can someone give a meaning to the formula on page 8 of in
http://www.scipress.org/journals/forma/abstract/2201/22010005.html
(related to A003437 as it seems)
when the index reaches the upper limit k=n and a division by zero occurs in
the square bracket?
