Presentation

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

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

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

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

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