Presentation

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

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

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

GAP

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

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