The polynomial [read slowly] x to the n plus y to the n is irreducible over the reals if and only if n is one of these numbers. Every known almost perfect number is one of (-5[2])these numbers. (-5[2])The cardinality of the power set of (-5[1])any finite set is one of (10[1])these numbers. These numbers appear in the exponent in the formula for Fermat numbers, while Mersenne primes are defined as being one less (-5[1])than (-5[1])these numbers. The sum along any row of (10[1])Pascal’s triangle is equal to one (10[1])of these numbers. These are the only integers with no odd prime factors. In binary, these numbers consist of a one followed by (10[1])all zeros. For 10 points, name these numbers which include 4, (10[1])8 (10[1])and 16, obtained by repeated multiplication by the smallest even (10[1]0[1])number. ■END■
