• Values of n such that N=(an+1)(bn+1)(cn+1) is a 3-Carmichael number (A087788), where a,b,c = 1,2,33.at n=12A064253
• In the interior of a regular 2n-gon with all diagonals drawn, the number of points where exactly three diagonals intersect.at n=37A101363
• a(n) = n*(n + 1)*(17*n - 14)/6.at n=26A237617
• Values n, where n = p * q, and n, p, and q together contain all 10 digits at least once, and no digit is in more than one of n, p or q.at n=34A253173
• Take apart the sides of each of the integer-sided triangles with perimeter n (at their vertices) and rearrange them orthogonally in 3-space so that their endpoints coincide at a single point. a(n) is the total volume of all rectangular prisms enclosed in this way.at n=37A308233
