• Number of permutations of 5 copies of 1..n with all adjacent differences <= 1 in absolute value.at n=4A177301
• Number of permutations of n copies of 1..4 with all adjacent differences <= 1 in absolute value.at n=5A177316
• Start of record gaps between sums of two squares.at n=18A297350
• Number A(n,k) of sequences with k copies each of 1,2,...,n avoiding absolute differences between adjacent elements larger than one; square array A(n,k), n>=0, k>=0, read by antidiagonals.at n=49A331562
• First occurrence of difference n between two consecutive terms of A000404. a(n) gives the lower term. The upper term is A355238.at n=33A355237
