The number of arrays (or subsets) that can be formed from a set of 42 elements is determined by the formula (2^n), where (n) is the number of elements in the set. Therefore, for 42 elements, the number of possible arrays is (2^{42}), which equals 4,398,046,511,104. This includes all possible combinations, including the empty set and the full set itself.
