Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

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

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

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