    All I can say is that P(ℝ) refers to a power set of ℝ (all rational numbers). Although I don’t know what n stands for in Pⁿ(ℝ)

    Basically P(A), where A = {1,2,3}, equal {Φ,1,2,3,(1,2),(2,3),(1,3),(1,2,3)}

      Yeah this was a possibility I was thinking as well. The superscript n could just be n recursive applications, but then n is still not defined. It’s one of the things that makes me thing that it’s just nonsense. Also, how do you do math on Lemmy? Can you just use LaTeX math syntax or did you copy those symbols?
