Presentation

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

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

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

GAP

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