• Strong pseudoprimes to base 41.at n=19A020267
• Strong pseudoprimes to base 93.at n=25A020319
• Numbers k such that the continued fraction for sqrt(k) has period 91.at n=29A020430
• Take pairs (x,y) with Sum_{j = x..y} j = concatenation of x and y. Sort pairs on y then x. This sequence gives x of each pair.at n=42A070152
