This number is a composite.
132 and its reversal (231) are both divisible by the prime 11 (132/11 = 12, 231/11 = 21).
Note that the resulting quotients are also reversals. [Gevisier]
The concatenation of its three distinct prime factors (2, 3, and 11) forms primes in three ways: 2311, 2113, and 1123. [Trotter]
π(132) = 11 + 33 + 22. [Firoozbakht]
The smallest composite number such that all its digits are
necessary to write its prime factors. [Capelle]
