Ascher Databook Notes:
- This is one of several khipus acquired by the Museum in 1907 with provenance Ica. For a list of them, see AS100.
- By spacing, the khipu is separated into 2 groups of 7 pendants each. Both groups have the same color pattern: MB, EB, B, MB: W, B: W, W, W.
- With the exception of the first position, values in both groups are in the same relative order. Specifically:
P_{i7} > P_{i2} > P_{i4} > P_{i3} > P_{i5} > P_{i6} for i=(1, 2)
- With the exception of the 6th position, the values of group 2 are greater than those in corresponding positions in group 1.
P_{2j} > P_{1j} for j=(1, 2...,5,7)
- The last value in group 1 is the sum of 3 other values in the group:
P_{17} = P_{11} + P_{13} + P_{16}
- a) Two pairs of values in group 1 have the same sum. In both pairs, the values are 3 positions apart.
P_{11} + P_{14} = P_{13} + P_{16}
b) With a discrepancy of 1, the sum is the same for a pair of values in corresponding positions in both groups.
P_{13} + P_{16} ≈ P_{23} + P_{26}
