• Trajectory of 3 under map n->37n+1 if n odd, n->n/2 if n even.at n=21A037116
• "Stapled" intervals are defined in A090318. Call a stapled interval "maximal" if it is not a proper subinterval of any other stapled interval. Sequence gives starting points of maximal stapled intervals.at n=21A130170
• "Stapled" intervals are defined in A090318. Call a stapled interval "minimal" if it does not contain any proper stapled subinterval. Sequence gives starting points of minimal stapled intervals.at n=21A130171
• a(n) = 40*(200*n - 49).at n=29A157652
• Starting points of stapled intervals of length 17.at n=15A194585
