Ascher Databook Notes:
 This is one of several khipus acquired by the Museum in 1907 with provenance Ica. For a list of them, see UR1100.
 By spacing, the khipu is separated into 7 groups of 7 pendants each (with the exception of the last group which has only 6 pendants). Each group has a top cord which is attached to the main cord j ust af ter the third (groups 2, 3, 7) or fourth (groups 1, 4, 5, 6) pendant.
 In groups 1, 2, 5, 6, 7, all pendants in a group are the same color.
 Each top cord differs in color from the pendants of the associated group. All of the top cords are zerovalued (or blank).
 In all groups where it exists, the 7th pendant is zerovalued (or blank). The nonzero values are restricted to 546663 in group 1 and to 134356 in the other 6 groups.
 With a discrepancy of 1, the sum of the values in the 4th position in each group equals the sum of the values in the 5th positions. Also, each has a subsum of 1000. That is:
\[ \sum\limits_{i=1}^3 P_{i4} = \sum\limits_{i=4}^7 P_{i5} = 1000 \]
\[ \sum\limits_{i=1}^7 P_{i4} = \sum\limits_{i=1}^7 P_{i5} \]
 The sums of the last 3 values in groups 2 and 3 are equal:
\[ \sum\limits_{j=4}^7 P_{2j} = \sum\limits_{j=4}^7 P_{3j} \]
