Customizations for short PLL

[reif]

I propose the following customizations for PLL. To my knowledge, the are the shortest in half-turn-metric. Unergonomic cube rotations are not needed.

F-Permutation:

M U2 r' U l' U2 r U' r R2 U2 R2

G-Permutation:

l2 U' L2 U' F2 L' U' R U2 L' U l

R-Permutation:

R2 U l U R U' l' U' l U2 R' U2 R

T-Permutation:

U2 r' U2 r U2 x U2 r U2 r' U2

Do you know shorter or more ergonomic versions?

What's up with all the double-layer turns? By your logic I can say I have an ergonomic Y perm (and J perm and T perm) too: U Lw U' R' U' R U Lw' U' Lw U R' U' Lw' U R U'. It's just the standard alg.

I dunno what F perm that is. The standard G perm is HTM optimal and shorter than yours in terms of QTM, and yours doesn't even have the AUF included. Your R perm is just the inverse of the standard alg minus the AUF. And your T perm is just the FMC one.
