• "Kaprekar quadruples": digits of X^4 taken D at a time sum to X (where D is number of digits in X.)at n=22A171493
• Triangle read by rows: T(n,k) is the number of permutations of [n] having no 3-sequences and having k successions (0 <= k <= floor(n/2)); a succession of a permutation p is a position i such that p(i +1) - p(i) = 1.at n=32A180185
• Triangle read by rows: T(n-1,k), where n >= 2 and 1 <= k <= floor(n/2), is the number of permutations of (1, 2, ..., n) having k consecutive pairs but no consecutive sequences of length greater than 2.at n=21A289632
