Presentation

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

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

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

GAP

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

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