You are going the make the BL square but the edge/s needed are stuck in the "right block". How many unique cases if I were to solve the square while preserving the DR corners?

Next question. I'm going solve the the FL pair while solving CP. How many unique cases are there including when the edge is stuck?

The L block is done. I'm going solve the BR square. Hoe many unique cases are there that solves it while preserving the DFR corner?

Note everytime I say preserve the DR corners, I just want to preserve their permutation.

Last question. The F2L corner is inserted ( its orientation isn't necessarily solved ) CP and EO is solved. How many unique cases?
