Appears in sequences

• Sequence (a(n): n >= 1) that shifts left 2 places under the "CIK" (necklace, indistinct, unlabeled) transform and satisfies a(1) = a(2) = 1.at n=16A032202
• Number of partitions of n with equal nonzero number of parts congruent to each of 2 and 4 (mod 5).at n=51A035570
• Numbers that are the products of distinct substrings (>1) of themselves and do not end in 0.at n=30A059470
• Numbers not ending in 0 which are the product of two substrings of themselves. The substrings may be equal, but each must be greater than 1.at n=9A066217
• Terms in A046034 which are pairwise products of terms in A046034.at n=28A153446
• Triangular array of numbers of 2-polymatroids of rank k on n labeled points, for n>=0, 0<=k<=2n.at n=29A256158

• a(n) = n*((4*n + 1)*(7*n - 4) + 15*n*(-1)^n)/48.at n=35A302766
