In the formula for A139400 it seems
that the coefficient of a(n-22)
should be equal to that of a(n-10)
and not equal to those of a(n-21)
and a(n-11). Also the signs seem
to be wrong. Also it's misleading
to call 780 the seventh term of
A001353. It is the sixth (involving
P_6); the zeroth is 0 and the first
is 1.
Does anyone know the correct recurrence,
&/or any more terms? R.
