Two consecutive Prps (100001 digits) with 25206!+p(4114)
Gap = 92500

PFGW Fermat Prp b=3,7 and BLS test :
PFGW Version 20040817.Win_Dev (Beta 'caveat utilitor') [FFT v23.8]

Primality testing 25206!-p(5447) [N-1/N+1, Brillhart-Lehmer-Selfridge]
Running N-1 test using base 2
Running N-1 test using base 7
Running N+1 test using discriminant 13, base 8+sqrt(13)
25206!-p(5447) is Fermat and Lucas PRP! (23903.7576s+0.2040s)
