• Cycle class sequence c(2n) (the number of true cycles of length 2n in which a certain node is included) for zeolite APD = AlPO4-D [Al16P16O64] starting from a T1 atom.at n=6A018980
• Number of signed weighted Euler trees with total weight n (associated to even switching classes of matrices of order 2n).at n=9A110886
• Triangle read by rows: T(n,k) is the number of paths of length n with steps U=(1,1), D=(1,-1) and H=(1,0), starting at (0,0), staying weakly above the x-axis (i.e., left factors of Motzkin paths) and having k peaks (i.e., UDs), 0 <= k <= floor(n/2).at n=44A132893
