Presentation

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

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

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

GAP

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

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