• Number of symmetric, reduced unit interval schemes with n+1 intervals (n>=1).at n=25A005213
• Construct triangle in which n-th row is obtained by expanding (1 + x + x^2)^n and take the next-to-central column.at n=11A005717
• Multiplicity of trivial character in V_n, where V = Sum V_n is the graded module for the Monster simple group.at n=46A014810
• Triangle read by rows: T(n,k) is the number of ternary words of length n on {0,1,2} having k drops (n>=0, k>=0). The drops of a ternary word on {0,1,2} are the subwords 10,20 and 21.at n=47A120906
• Triangle read by rows: T(n,k) is the number of paths in the first quadrant from (0,0) to (n,0), consisting of steps U=(1,1), D=(1,-1), h=(1,0) and H=(2,0), having k H steps (0<=k<=floor(n/2)).at n=50A132280
