Presentation

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

A minimal faithful permutation representation — 7 generators on 28 points:

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

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