Presentation

minimal degree	μ(G) = 56
transitive degree	μ_t(G) = 5616

A minimal faithful permutation representation — 2 generators on 56 points:

(1,2,3,4,5,6,7,8)(9,16,15,14,13,12,11,10)(17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43)(44,45,46,47,48,49,50,51,52,53,54,55,56);(1,9,5,13)(2,10,6,14)(3,11,7,15)(4,12,8,16)(18,43)(19,42)(20,41)(21,40)(22,39)(23,38)(24,37)(25,36)(26,35)(27,34)(28,33)(29,32)(30,31)(45,56)(46,55)(47,54)(48,53)(49,52)(50,51)

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