Recursion
You may be looking for Recursive.
Recursion explained. (TV: Castrovalva)

Recursion was the concept that ideas and concepts, as Nyssa put it, "fold back on themselves". Trying to come to grips with the concept, Tegan surmised that "if we had an index file we could look it up in the index file under 'index file'".

When Mergrave assured the Fifth Doctor that he was telling the truth because "I maintain that I am, and I am a man of my word," the Doctor called it a "perfect example of recursion".

The Doctor later realised that Castrovalva itself was — as a mathematical construct of the Tremas Master — inherently recursive. The Master intended to trap the Doctor there as the recursion folded in on itself and the reality collapsed. (TV: Castrovalva [+]Loading...["Castrovalva (TV story)"])
