Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 16

A minimal faithful permutation representation — 5 generators on 16 points:

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

Polycyclic presentation:

2^10|a^2=i,d^2=j,h^2=j,d^a=dh,d^b=dg,d^c=df,e^a=ei,e^c=ej,f^a=fi,f^b=fij,g^c=gi,g^f=gj,h^c=hij,h^d=hj,h^e=hj,h^f=hj,i^d=ij
