Presentation

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

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

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

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

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