1. Sum indicates the overall sum of the three numbers constituting a triplet; Log sum reflects the logarithm of this overall sum; Sum log denotes the sum of the logarithms of the individual numbers; Distance # 3-# 1 gives the absolute distance between the two outer numbers of the triplet, correspondingly for the other distances; Parity # 1/2/3 reflects the "average" parity of the respective numbers (even coded by +1, odd coded -1). Mean parity indicates the average parity of the three numbers and Parity homogeneity indexes whether all three numbers have the same parity or not (coded +1 vs. -1, respectively); Decade crossing indicates whether a triplet crosses a decade boundary (coded +1 for decade crossing, -1 for no decade crossing); Decade inclusion denotes whether the triplet involves a multiple of 10 or not (coded +1 vs. -1, respectively).
