Appears in sequences

• Number of -4..4 arrays X (0..n-1) of n elements with zero sum and elements alternately strictly increasing and strictly decreasing.at n=7A200053
• Squarefree numbers differing by more than 3 from any other squarefree number.at n=8A268332
• Starting at n, a(n) is the total number of moves made to the right according to the following rules. On the k-th step (k=1,2,3,...) move a distance of k in the direction of zero. If the number landed on has been landed on before, move a distance of k away from zero instead.at n=38A324660
• The successive remainders of the division by (a(n) + a(n+1)) of concat(a(n),a(n+1)) rebuild the sequence itself.at n=31A341037
• Lesser of 2 successive tetraprimes (k, k+4) sandwiching three consecutive not squarefree numbers.at n=31A367791
