	I generated terms for this sequence using the following
Mathematica program:
CoefficientList[Series[1/(1-2 x-3 x^2+x^3+x^4),{x,0,30}],x]
	The terms that program generates are: 1, 2, 7, 19, 56, 160, 462,
1329, 3828, 11021, 31735, 91376, 263108, 757588, 2181389, 6281058,
18085587, 52075371, 149945056, 431749580, . . .
They do not match most of the terms given in the OEIS.  Is the
definition (Name) of the sequence correct, or is there something I'm
missing?
	Best,
	Harvey
