For "Roman XV" I've entered "Arabic 15" and got rejected.

"15" was accepted, though. Manual password guessing is not much fun - reminds me of school too much.

Yeah, and it takes "prime numbers" but not "primes". Kind of annoying.

"ramanujan" was pretty pretentious

[treuherz]

It taking "ramanujan" and not "ramanujan-hardy" put me off it

[katastic]

That's the one that confused me.

And "infinity" but not "infinite"

[ehnto]

Ah. That explains where I got stuck.
