Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 512

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

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

GAP

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

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