Presentation

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

A minimal faithful permutation representation — 3 generators on 22 points:

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

Polycyclic presentation:

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