Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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

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

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