Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 28 points:

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

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

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