Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 7 generators on 30 points:

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

GAP

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

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