Dear Sequence fans,
I wrote the following PARI function
isleastnonwiefpsp(n, b) = if(Mod(b, n^2)^(n-1)==1, return(0),
forcomposite(c=1, n-1, if(Mod(n, c^2)^(c-1)!=1, return(0))), return(1))
When I try to execute this function, I get a strange error. For example,
when I execute the following function call
isleastnonwiefpsp(8, 12)
I get the error
_multi_if: bug in PARI/GP (Segmentation fault), please report.
Any ideas what the problem is here?
Felix
