• Triangle read by rows: T(n,k) is number of ternary words of length n and having k runs of 0's of odd length (0 <= k <= ceiling(n/2); a run of 0's is a subsequence of consecutive 0's of maximal length).at n=49A119914
• Number of ternary words of length n and having exactly one run of 0's of odd length.at n=12A119915
• Permutations of 123456: Numbers having each of the decimal digits 1,...,6 exactly once, and no other digit.at n=8A178476
• List of André permutations of the first kind.at n=28A278982
• a(n) = minimal value of n+k (with k >= 1) such that the concatenation of the decimal digits of n,n+1,...,n+k is divisible by n+k+1, or -1 if no such n+k exists.at n=17A332584
