Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 7 generators on 28 points:

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

GAP

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

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