How many subsets can be made from a set with 6 elements?

If a set has six elements, for example {A, B, C, D, E, F}, then it may have the following subsets:

- the set itself

- 6 sets of five elements

- 15 sets of four elements

- 20 sets of three elements

- 15 sets of two elements

- 6 sets of one element

- 1 set with no elements (the null set),

for a total of 64 sets, which is 2^6, or 2 to the 6th power.
