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

GAP

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