26 = 2 x 13.
26 is the only integer sandwiched between a square (25) and a cube (27).
26 is the smallest non-palindromic number whose square is palindromic: 262 = 676.
26 is equal to the sum of the digits of its cube: 263 = 17,576 and 1 + 7 + 5 + 7 + 6 = 26.
26 (together with 11) cannot be represented as the sum of less than six hexagonal numbers from the sequence 1 6 15 28 45 . . . .
26 has a representation as a sum of two squares: 26 = 52 + 12.
26 is the smallest number with three representations as a sum of three distinct primes: 26 = 2 + 5 + 19 = 2 + 7 + 17 = 2 + 11 + 13.

The number 0 is also sandwiched between a perfect square (1) and a perfect cube (-1)
