Presentation

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

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

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

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