Presentation

minimal degree	μ(G) = 16
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 16 points:

(2,4)(6,8)(14,15);(5,6,7,8)(11,14,16,15);(9,10)(11,15,16,14)(12,13);(1,2,3,4)(9,11)(10,14)(12,15)(13,16)

Polycyclic presentation:

2^10|b^2=h,c^2=i,d^2=ef,g^2=j,b^a=bh,c^a=ci,d^a=de,d^b=dg,d^c=df,e^b=ei,e^c=ej,f^b=fi,f^c=fj,g^a=gi,g^c=gij,g^d=gj,g^e=gj,g^f=gj,h^d=hj,i^d=ij
