Presentation

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

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

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

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

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