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

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