• "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=9A130170
• "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=9A130171
