Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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

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