Define E to be the empty set and further define F = {E}, G = {F}, H = {E, F}, and I = {E, F, G,H}. (a) Describe each of these five sets as lists using only the symbols ∅, {, and }. (b) What is the size of each of the five sets? (c) If X and Y are each any one of the five sets, we can form the statements “X ∈ Y” and “X ⊆ Y”. Exactly which of these fifty possible statements are true?
