[Maximilian Hasler]

The following sequence is related.
In fact its description could be simplified to:

First element of the 2x2 matrix [0,1;2,3] to the n-th power

Any advice for/against this simplification ?

A106434 	 	The first entry of the vector v[n]=Mv[n-1], where M is the
2 x 2 matrix [[0,2],[1,3]] and v[1] is the column vector [0,1].
	0, 2, 6, 22, 78, 278, 990, 3526, 12558, 44726, 159294, 567334,
2020590, 7196438, 25630494,...

 CROSSREFS   	Equals 2*A007482(n-2), for n>1.
