Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 6 generators on 30 points:

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

GAP

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

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