Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 160

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

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

Polycyclic presentation:

2^8,5^2|a^2=g,c^2=e,d^2=e,g^2=h,b^a=bgh,c^a=ch,d^a=dg,d^b=df,g^b=gh,g^d=gh,i^a=i^4,i^c=i^3,i^d=i^3,i^e=i^4,j^a=i^3j,j^c=j^3,j^d=j^3,j^e=j^4
