• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 18.at n=19A031696
• Triangle T(n,k) of number of digraphs with a quasi-source on n labeled nodes and with k arcs, k=0,1,..,n*(n-1).at n=30A057272
• Where records occur in A074078.at n=8A074098
• a(n) = Fibonacci(n) mod n^3.at n=44A132636
• 324n^2 + 2n.at n=9A158271
• a(n) = 400*n^2 + 20.at n=9A158601
• a(0)=1, a(1)=3, and the INVERT transform of the sequence deletes the 3.at n=9A259845
• Numbers k such that (11*10^k + 49)/3 is prime.at n=27A272999
• Draw a regular n-gon and the enclosing circle, then for each pair of vertices X, Y, draw a circle with diameter XY; the union of these figures is the graph H_n; sequence gives number of edges in H_n.at n=19A370979
• Consecutive internal states of the linear congruential pseudo-random number generator (421*s + 54773) mod 259200 when started at 1.at n=23A383129
