Presentation

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

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

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

GAP

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

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