No, my wording was what I meant. As the other reply points out, it is the usual case for a set of consecutive integers to have one member coprime to all the others. E.g., {2,3} has 2 coprime to 3. {12,13,14,15} has 13 coprime to 12, 14, and 15. {24,25,26,27,28} has 25 coprime to 24, 26, 27, and 28. {48,49,50,51,52} has 49 coprime to 48, 50, 51, and 52.
