I don’t know the proper name for it, but there’s also “Z” frames- where one set of motors is right side up on arms attached to the bottom plate, and the other set of motors is upside down in a pusher configuration on arms attached to the top plate.
Toothpicks (or picks)- lightweight, skinny arms, usually with a canopy for the camera.
There’s also x8- 4 arms, 8 motors, one motor up and one motor down on each arm. Usually seen on cinelifters or anything made to carry a heavy payload.
Tricopters (3 motors, rear motor is usually attached to a servo).
Then there’s a “bone” frame, with two motors right side up, two motors upside down, squeezed into a line that looks kinda like a flying stick. I never could understand how those things can fly, but I kinda want to build one:
Oscar’s guide at the link below goes over a number of different frame types:

Disclaimer: I don’t know wtf I’m talking about.
I wish I could get the smell of burnt electronics out of my nose.
