• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 32.at n=12A031710
• All 81 combinations of prefixing and following a(n) by a single digit are nonprime.at n=33A032734
• a(n) cannot be prefixed or followed by any digit to form a prime ('empty' prefixes allowed).at n=10A032736
• Interprimes (A024675) which are of the form s*prime, s=13.at n=19A075288
• a(n) = 169*n^2 + 13.at n=16A158548
• Number of n X 4 0..1 arrays with rows and columns lexicographically nondecreasing read forwards, and nonincreasing read backwards.at n=25A201371
• Numbers k such that the factor method (A064097) for computing the k-th power has fewer multiplications than Knuth's power tree method (A114622).at n=2A256653
• Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 363", based on the 5-celled von Neumann neighborhood.at n=40A268154
• The sum of the numbers on straight lines of incrementing length n when drawn over numbers of the square spiral, where each line contains numbers which sum to the minimum possible value, and each number on the spiral can only be in one line. If two or more lines exist with the same sum the one containing the smallest number is chosen.at n=37A340974
