Presentation

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

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

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

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

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