Dale,
May I suggest the following designation for a few of the un-named pieces.
Hippogriff = 1,1,2 leaper
Wyvern = 1,2,2 leaper
These are the classic names for these two 3D Chess pieces. The first
given by Kogbetliantz, although he eventually extended the leap of this
piece in order to remove its being bound to a single diagonal pattern.
The second was given by V. R. Parton.
