Presentation

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

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

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

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