4x4 PLls

there is also a way to avoid PLL parity if you have OLL parity, but the recognition is a disaster. most just learn the full 3x3 PLL algs and then the PLL parity alg. i use a lot of the short ones given at dans cubing site (link in post above). ones like (pll alg) U' (r perm). . . but all these alg are are early recognition of the PLL with the opposite 2 swap taken into consideration. for me, while im recognizing the PLL, i can guess the PLL after the parity. T perm is probably the easiest one. you see 2 corner swap and a 2 edge swap, but then an extra edge swap (like a H perm), so when you swap 2, you see the final result before you perform the parity!
