• Number of fixed properly-4-dimensional polyominoes with n cells.at n=6A006764
• Define k(0) = 2 and k(m) = m^2-k(m-1) for m >= 1. This is a list of those terms k(m) for which k(m)+1 and k(m)-1 are both in A008578 (primes including 1).at n=13A154734
• Number of n-cell polycubes that are proper in n-3 dimensions.at n=4A191092
• Triangle read by rows: DX(n,d) = number of properly d-dimensional polyominoes with n cells, modulo translations (n>=1, 0 <= d <= n-1).at n=25A195739
• Numbers k such that in a rotated-square spiral with positive integers (A215468) among k's eight nearest neighbors five or more are primes.at n=37A215471
