This is a list of Bram's sphere type twisty puzzle geometries that (potentially) have two or more 
corner types simultaneously. For details and notation, see the forum thread at 
http://twistypuzzles.com/forum/viewtopic.php?f=1&t=31829 

The list is divided into several sections. You will need to play around with the cut depths to get
these to work. So far, most of the ones I've tried have worked for me after a bit of fiddling. Note
that some of these are trivial, e.g. just related to the symmetries of the cube, but others are
quite unexpected.

In this list, sides can have up to 20 stops, and pieces with symmetries up to 8 are considered.

The pale Usher--threadbare in coat, heart, body, and brain; I see him now. He was ever dusting his old lexicons and grammars, with a queer handkerchief, mockingly embellished with all the gay flags of all the known nations of the world. He loved to dust his old grammars; it somehow mildly reminded him of his mortality.

"WHALE.... Sw. and Dan. HVAL. This animal is named from roundness or rolling; for in Dan. HVALT is arched or vaulted." --WEBSTER'S DICTIONARY
