Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 1024

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

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

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

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