Presentation

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

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

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

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

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