Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 80

A minimal faithful permutation representation — 4 generators on 22 points:

(6,11)(10,12)(13,14,17,15,16)(18,19,20,22,21);(6,10)(7,8)(11,12);(2,4);(1,2)(3,4)(5,6,7,10,9,11,8,12)(14,15,16,17)(19,20,21,22)

Polycyclic presentation:

2^8,5^2|a^2=e,e^2=h,f^2=h,b^a=bg,c^a=cf,d^a=dh,e^c=eh,f^c=fh,i^a=i^2,i^e=i^4,j^a=i^3j^3,j^e=j^4
