Presentation

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

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

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

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

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