Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 24 points:

(11,15)(14,16)(17,18)(19,20)(21,23)(22,24);(6,8)(11,15)(14,16)(17,19,21,24)(18,22,23,20);(10,13)(14,16)(19,24)(20,22);(9,10)(11,16)(12,13)(14,15)(17,20)(18,19)(21,22)(23,24);(5,6)(7,8)(9,11)(10,14)(12,15)(13,16)(17,18)(19,20)(21,23)(22,24);(3,4);(1,2)(3,4)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
