The structure is one of the five wedges of A222180.
The sequence gives the number of pentagons in the structure after n-th stage. A222177 (the first differences) gives the number of pentagons added at n-th stage.
Also P-toothpick sequence starting near of the vertex of an infinite 72-degree wedge, since each pentagon can be replaced by a P-toothpick.
First differs from A152998 at a(10).
