Frames for Kirkman triple systems
We introduce the idea of a `frame' for a Kirkman triple system: loosely speaking, a frame is a Kirkman system with `holes'. We construct many frames for Kirkman triple systems. We then apply these frames to the construction of Kirkman triple systems with subsystems. We construct a system of order v containing a system of order w, for all admissible \(v\geq 4w-9\), with two exceptions.
