Ascher Databook Notes:
1. AS074-AS080 are associated. See AS074 for discussion.
2. By spacing, there are 15 groups and 2 single pendants (PSS and P68). The single pendants are viewed as markers since there are larger spaces between ad­jacent groups where they occur, and because both of them are blank. Hence, by markers and number of pendants per group, the khipu is separated into 3 parts. The first part is 9 groups of 6 pendants each; the second is 4 groups of 3 pen­dants each; and the last part is 2 groups of 3 pendants each.
3. All groups in Part I have the same color pattern: BS, PB, W, W, MB, AB. The groups in Parts II and III have the same color pattern as each other. Their pattern is a subset of the pattern of Part I: W, W, MB.
4. The pattern of values on the pendants in Parts II and III are similar:
$P_{i1}=P_{i3}\;\;for\;i\;=\;(10,11,12,13,14)$
$P_{i1}=P_{i2}-1\;\;for\;i\;=\;(10,11,12,14,15)$
Thus:
$P_{i1}=P_{i2}-1\;=P_{i3}\;for\;i\;=\;(10,11,12,14)$
