A Saouter number is a type of Generalized Fermat number. Numbers of this type have the form

An=43n+23n+1

In the notation of John Cosgrave, the Saouter numbers are generated by the sequence Fn,2. Due to this, these numbers share similar properties to those held by Fermat numbers. These numbers were named by Tony Reix[1][2] after Yannick Saouter, who studied these numbers[3].
