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

GAP

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

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