I've been thinking about this all day and then it hit me , Renault had what was called a ravignaux planetary assembaly that had compound planet gears ..used on a type 4139 trans
I'm looking for one of my old AMC school books,[ they were way better than the Frenchie's manuals ] for a blow up of it. if I remember correctly it had 2 sun gears , 1 annulus gear and compound planet gears.
I'll have to dig thru the stuff I had hoped I'd never have to use again!

Found a description and an excellent engineering web site.
