Hi Guys, I'm back again.....
So, I've worked out the missing solution...now my algs looks like that:

UF  DB (U' M2) (R U' R' U) (M U') (R U r' U)
BU  DB x (U' M2) (R U' R' U) (M U') (R U r' U) x '
UF ® BU x' (U' M2) (R U' R' U) (M U') (R U r' U) x

DB  UF (U' r U' R' U) (M' U') (R U R') (M2 U)
DB  BU x (U' r U' R' U) (M' U') (R U R') (M2 U) x'
BU  UF x' (U' r U' R' U) (M' U') (R U R') (M2 U) x

BD  UF (U M' U' M) U2 (M U M' U)
DB  UB x (U M' U' M) U2 (M U M' U) x'
UB  FU x' (U M' U' M) U2 (M U M' U) x

UF  BD (U' M U' M') U2 (M' U M U')
UB  DB x (U' M U' M') U2 (M' U M U') x'
FU ® UB x' (U' M U' M') U2 (M' U M U') x

UB  UF (U M U M) U2 (M' U M' U')
DB  FU x' (U M U M) U2 (M' U M' U') x

UF  UB (U M U' M) U2 (M' U' M' U')
FU  DB x (U M U' M) U2 (M' U' M' U') x'

BU  FU (M' U2 M U2)
BD  FU x (M' U2 M U2) x'

FU ® BU (U2 M' U2 M)
FU  BD x (U2 M' U2 M) x'

UB  BD U2 (D M' D M') U2 (M' D M' D)
BD  UB (D' M D' M) U2 (M D' M D') U2
BD  BU (M U2 M U2) M2
BU  BD M2 (U2 M' U2 M')

And of course:

UB s U2 M2 (s) M (s)' M U2 Switch RU and LU
s UB U2 M' (s) M' (s)' M2 U2

UF s M2 (s) M (s)' M
s UF M' (s) M' (s)' M2
s FU (s) M2 (s)' M U2 M U2

DB s M2 (s) M' (s)' M'
s DB M (s) M (s)' M2
s BD (s) M2 (s)' U2 M' U2 M'

The two main algs for UF-> DB and Inverse seems quite long but are actually pretty fast...

I also had another Idea...that could be useful for somebody who whants to keep algs memorisation at the minimum:

For UF-> DB (and Inverse) you could also do "F2 then Alg of UF-> BD and thatn F2 again....

That means that the actual memorization of algs, would become of..about five? If you don'consider the really easy 4 moves one... of course.

I hope that can be useful for you...I don't know if that is gonna be faster than Maky's commutators way...I think so though.....

Have a grat Day!

Federico
