Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 256

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

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

GAP

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

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