Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 7 generators on 28 points:

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

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