Our analysis of spinor coordinate examples shows notable differences between Gorenstein ideals with 4, 6, 7, and 8 generators compared to those with more generators. Also, we discuss the codimension four Gorenstein ideals resulting from doubling codimension three perfect ideals. We see, in particular, the construction of generic doublings of almost complete intersection perfect ideals of codimension three.
