Presentation

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

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

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

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