Template:Generalized Fermat number

Description

Template Generalized Fermat number

Collect the data of a Generalized Fermat number a²ⁿ + b²ⁿ, for b=1 this is a Fermat number a²ⁿ + 1.

Prototype

{{Generalized Fermat number
|GFNa=
|GFNb=
|GFNn=
|GFNFDBid=
|GFNDigits=
|GFNFactors=
|GFNState=
|GFNRemarks=
}}

Parameters

If 'GFNa'+'GFNb' is even, the numbers are always divisible by 2 and so 2 is not given as factor here.

If 'GFNFDBid' is given, a link to the FactorDB is created, otherwise only the number in standard notation is given.
