Starting from Matthew's position I've solved it in 315 twists. Log is here:=

Hi again,
I've decided to skip 4^4 level and jump immediately to 5^4. Algorithm was=
almost the same as I used in 3^4: first I build 4x1x1x1 columns (in "scram=
bled" order), then extend them to 5x1x1x1 and at last solve the remaining 5=
^3 puzzle. There was no unexpected "parity problems", but in general it was=
difficult, especially the first stage - sometimes it took 30 minutes to se=
lect cubes and their positions for the next step and to make 10-15 twists )=
))
