Presentation

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

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

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

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

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