Presentation

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

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

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

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