Presentation

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

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

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

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