P, Q and R are three points located on a circle L with diameter 4 and satisfying PQ = QR. Point S is located inside L in such a manner that QR = RS = SQ. The line passing through P and S intersects L at the point T.

Determine the length of ST.

Very nice plane geometry solution which is precise and yet concise and compact.

Consequently, I confirm having hyperlinked your methodology in my solution.
