Presentation

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

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

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
