Warning: The computation of the numbers in the column labeled "Permutation rank" is extremely complicated. For reasons of efficiency we had to rewrite the code for computing c(w,w'), and the results reported in this column may be very slightly different than if we had used the original WRR program. For the same, results reported in this column may be slightly inconsistent with results reported elsewhere in this paper, where the original WRR program was used.

Comment: The entries in this table are sorted by their P₂ score and not by the more reliable permutation rank. Computing all permutation ranks was simply not feasible at the time of writing of [WRR2], and we believe they could not have had this data available. To get these numbers we had to run our more efficient program for several days on about 50 very fast workstations in parallel, using the second author's scheduling tool autoson. (The computation of just the P₂ score without computing permutation ranks was easily feasible at the time of writing of [WRR2]. We made this computation on a single CPU using the program supplied to us by WRR, long before we were able to compute the permutation ranks.) Sorting by permutation ranks, תפש, םע and בתכ are number 1, 3, and 9 respectively. Not as good as 1-2-3, but still way too good to be a chance hit.
