S S M M M L L L

When a loop appears in the right thumb and a whorl in the left, the
sequence is:

S M L S M L S M L
- - - - - - - - -
I I I M M M O O O

V. _Second Subsecondary:_

SSS LLL.
--- to ---
SSS LLL

The sequence for filing the second subsecondary is as follows:

SSS SSM SSL SMS SMM SML
--- --- --- --- --- ---
SSS SSS SSS SSS SSS SSS

SLS SLM SLL MSS MSM MSL
--- --- --- --- --- ---
SSS SSS SSS SSS SSS SSS

MMS MMM MML MLS MLM MLL
--- --- --- --- --- ---
SSS SSS SSS SSS SSS SSS

LSS LSM LSL LMS LMM LML
--- --- --- --- --- ---
SSS SSS SSS SSS SSS SSS

LLS LLM LLL, LLL,
--- --- --- etc., to ---
SSS SSS SSS LLL

each group of the numerator becoming in turn the denominator for the
complete sequence of numerators as listed above.

VI. _W C D X Extensions:_

W xX3x.
- to ----
W xX3x

The sequence is as follows: Prints with _c_, _d_, or _x_ in any finger
other than the index fingers constitute the small-letter group. A
sample of the sequence follows:

W cWc xWd Wdx
cW cWd xWx Wxc
dW cWx W2c Wxd
xW dWc Wcd W2x
Wc dWd Wcx cW2c
Wd dWx Wdc cWcd
Wx xWc W2d cWcx

As may be readily seen, the sequence proceeds in the same fashion as
the a, t, r, small-letter sequence.

VII. Special Loop Extension used by the _Federal Bureau of
Investigation:_

111 777.
--- to ---
111 777

The following is a partial sequence for filing this extension:

111 112 113 114 115 116 117
--- --- --- --- --- --- ---
111 111 111 111 111 111 111

121 122 123 124 125 126 127
--- --- --- --- --- --- ---

131 132 133 134 135 136 137
--- --- --- --- --- --- ---
111 111 111 111 111 111 111

141 142 143 144 145 146 147

161 162 163 164 165 166 167
--- --- --- --- --- --- ---
111 111 111 111 111 111 111

171 172 173 174 175 176 177
