blsv
lsvb
svbl
vbls
bvsl
bvls
vlsb
vbsl
vlbs
sbvl
lvbs
lsbv
lbvs
slbv

I didn't check which ones are missing, but there should be 24 of them
4x3x2x1 = 24
looks like you went about just randomly
try a pattern
BLSV
BLVS
BSLV
BSVL
BVSL
BVLS that cares care of the 6 that start with B
Now put another letter at the beginning for 6 more
etc.
