Presentation

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

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

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

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

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