The sequence lists the minimal term of members of the array n=1 {0} n=2 {0,0} n=3 {1,0,1} n=4 {6,2,2,6} n=5 {37,18,15,18,37} n=6 {257,153,122,122,153,257} n=7{1998,1338,1081,990,1081,1338,1998} n=8 {17280,12449,10298,9210,9210,10298,12449,17280}. The j-th row above lists the number of permutations on {1,2,...,j} for which 1,2,3,...,j are not part of any LIS. An alternative sequence would list the maximal terms in the rows above as 0,0,1,6,37,257,1998,17280,...
