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:

WtoxX3x.
WxX3x

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 dW 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.
