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.
For the case (a,b) = (8,1) the number for Fn(8,1) div 22n+1 = 42n − 22n + 1 is given.
