WebA set with n =1 elements, e.g S1 = {x1} , clearly has only two subsets; S1 and the empty set ϕ. Thus it obeys our rule of 2n, as 21 = 2. To use induction, now we want to show if some given set with n elements has 2n elements, then a set with n + 1 elements has 2n + 1 elements. The answer is pretty clear after some thinking. WebIf you're willing to order the sets in this way, then the $n$th set contains element $m$ exactly when the binary expansion of the number $n$ has its $m$th-least significant bit …
