The article never says that the FBI or LA PD recognized Euler's theorem. The arson could've explained it in some of his emails or phone calls.

Well, the first reference Google turned up is considerably more obscure (by LATimes standards).
I'm trying to find an LAPD/FBI person who knows what Euler's totient function is!
BTW, I've asked one of my friends, who is an editor at the LATimes, to find out for me what the theorem really was, and how they recognized it.

Euler's Theorem states that if gcd(a,n) = 1, then a^phi(n) = 1 (mod n). Here phi(n) is Euler's totient function: the number of integers in {1, 2, . . ., n-1} which are relatively prime to n. When n is a prime, this theorem is just Fermat's little theorem. ----

From context, I'd guess e^(i pi) = -1.
