Most intricate of all the individual sequences is the small-letter sequence. It is less difficult if the following method is used:
1. Sequence according to the patterns in the index fingers, grouped
| A | to | W. |
| A | W |
When small letters are present, there are 25 possible combinations which can appear in the index fingers. They are as follows:
A T R U W
- - - - -
A A A A A
A T R U W
- - - - -
T T T T T
A T R U W
- - - - -
R R R R R
A T U R W
- - - - -
U U U U U
A T U R W
- - - - -
W W W W W
2. Within each group sequence:
a. The denominator, by—
(1) Count of the small letters (lesser preceding the greater).
(2) Position of the small letters (those to the left preceding those to the right).
