Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 256

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

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

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

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