Presentation

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

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

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

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

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