ATLAS: Exceptional group F4(2)

Order = 3311126603366400.
Mult = 2.
Out = 2.

Standard generators

Standard generators of F4(2) are a and b where a is in class 2C, b is in class 3C, ab has order 17, and ababababbababbabb has order 13.
An image of (a,b) under the outer automorphism is given by ((ab)^-5a(ab)^5, (abb)^-3bb(abb)^3).
Standard generators of the double cover 2.F4(2) are pre-images A and B where B has order 3 and AB has order 17.
Standard generators of F4(2):2 are c and d where c is in class 2E, d is in class 3AB, cd has order 40 (in fact this is in class 40B), and abababb has order 10.
Standard generators of the double cover 2.F4(2):2 are pre-images C and D where D has order 3.
