Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 32 points:

(1,2)(3,4)(5,6,7,8)(9,10)(11,14)(12,13)(15,16)(17,18)(19,21)(20,22)(23,24)(27,31)(29,32);(1,2,3,4)(5,6)(7,8)(10,13)(11,15)(17,18,21,19)(20,22,24,23)(27,31)(29,32);(11,15)(14,16)(18,19)(20,24)(25,26,28,30)(27,29,31,32);(2,4)(6,8)(9,11,12,15)(10,14,13,16)(17,19,21,18)(20,23,24,22)(25,26)(27,32)(28,30)(29,31);(1,2)(3,4)(5,6)(7,8)(9,10)(11,16)(12,13)(14,15)(17,20)(18,22)(19,23)(21,24)(25,27)(26,29)(28,31)(30,32)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
