Presentation

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

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

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

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