B. Secondary loop and whorl group:
R W.
- to -
R W
When no small letters are present, there are 9 possible combinations
which can appear in the index fingers. They are as follows:
R U W
- - -
R R R
R U W
- - -
U U U
R U W
- - -
W W W
At this point it is well to note that it may be preferable in some
instances where small files are concerned to use only a portion of the
classification formula in the filing sequence. In such cases, only
those parts of the filing sequence which are necessary should be used
along with the final and key.
III. _Subsecondary:_
III OOO.
--- to ---
III OOO
The sequence of the subsecondary is as follows:
III IIM IIO IMI IMM IMO IOI
--- --- --- --- --- --- ---
III III III III III III III
IOM IOO MII MIM MIO MMI MMM
--- --- --- --- --- --- ---
III III III III III III III
MMO MOI MOM MOO OII OIM OIO
--- --- --- --- --- --- ---
III III III III III III III
OMI OMM OMO OOI OOM OOO OOO,
--- --- --- --- --- --- etc., to ---
III III III III III III OOO
each numerator in turn becoming the denominator for the complete
sequence of numerators as listed above.
IV. _Major:_
The following sequence is used when loops appear in both thumbs:
S M L S M L S M L
- - - - - - - - -
S S S M M M L L L
When whorls appear in both thumbs the sequence is:
I M O I M O I M O
- - - - - - - - -
I I I M M M O O O
When a whorl appears in the right thumb and a loop in the left, the
sequence is:
I M O I M O I M O
- - - - - - - - -
