same exponents as OP, on the only working hardware I have at last check an android phone. I think it has a snapdragon processor, and PARIdroid was 2.11.0.1.5 edit2: seems my PARIdroid thinks they aren't prime though...

OP listed timings for 3 exponents in 2 separate posts: 23209,86243 and 216091. Which 2 of these are you talking about?

So instead of repeatedly computing x = x^22 (mod 2^p1), you set x = 4 and repeatedly computed x^22 without updating x ... so your final result should be x = 4, which means your x==0 of the final result should have come up 'false'. You didn't notice that?

I didn't know the exponents created primes. I haven't put CRG's MeVec script back on my device.
