• Numbers k such that k * (digit complement of k) is a square.at n=11A069000
• Determinant of the n X n matrix whose element (i,j) equals the |i-j|-th prime or if i=j, 0.at n=11A071079
• Numbers k for which the quotient q(k)=(k+rev(k))/abs(k-rev(k)) is an integer.at n=35A087993
• Consider the family of multigraphs enriched by the species of derangements. Sequence gives number of those multigraphs with n loops and edges.at n=8A098625
• Numbers which are proper divisors of the number obtained by cyclic right-shift by 2 positions.at n=5A166320
• Numbers k such that R(k)/k is of the form m/(m + 1), where R(k) is the digital reversal of k.at n=16A376260
